INSTALL PLATFORMS �► If your system does not include a platform,skip to'CONNECT RAMP SECTIONS'. Platform handrails are shown for clarity of how to orient platforms in various configurations. It is strongly suggested that all platforms and ramps be installed before installing handrails(see"HANDRAILS'section). 2.1.1. There are four basic platform arrangements(one or more of these platform arrangements may be used in an installation).All four require the same procedure for assembly except for FIG.2.3 which requires an additional PPPC(PLATFORM TO PLATFORM CONNECTOR). FIG.2.1 Platform in straight configuration. FIG.2.2 Platform in turn configuration. "FIG.2.3 Platforms in turn back configuration(two 5'x 4' platforms shown combined to make 5'x 8'turn back). FIG.2.4 8'x 5'turn back platform. FTG. 2.1 FIG. 2.2 FIG. 2.3 FIG. 2.4 Page 12 of 74 2.2. INSTALL SUPPORT TUBES AND FEET,THEN ADJUST PLATFORM HEIGHT 2.2.1. Siupport tubes,plugs,and feet come in pairs.Support tubes will come in lengths sufficient for the heights at specific locations. 2.2.2. Loosen all set screws in the platform corner pockets. 2.2.2.1 The set screws on the outside of the platform are for the platform support tubes. 2.2.2.2. The set screws on the inside of the platform (one above the deck and one below the deck)are for the handrail posts. 2.2.3. Tip the platform on its side,then slide the support tubes into the four platform corner pockets.Adjust the support tubes to the approximate platform height needed (FIG.2.5). PLUG--,, SUPPORT TUBE i FIG. 2.5 FOOT FOOT ATTACHMENT THUMBSCREW e SUPPORT TUBE SET SCREWS (2/CORNER POCKET) 2.2.4. Use supplied 3/16"Allen wrench to tighten the upper of the two set screws in the corner pocket,just enough to hold the support tube in place but do not over tighten (the second set screw will be tightened after.final height adjustments are complete). �- Platforms configured as a turn back platform(FIG.2.3)will have six tubes to adjust. A Do not attempt to walk on the platform until all support tube set screws have been tightened securely. 2.2.5. Place the platform (with support tubes attached) into the upright position. A Do not let the weight of the platform bear on the support tubes while tipping the platform upright. 2.2.6. 'Lift each corner of the platform and install a base foot on each support tube oriented !so that the foot extends under the platform (FIG. 2,5). Page 13 of 74 The feet can be oriented in other directions if necessary due to site conditions but may present a tripping hazard if not oriented under the platform. A It is the installer's responsibility to install the system in a manner which is safe for the persons on and around the system and clearly mark any hazards created by the installation. 2.2.7. Make sure the feet are fully engaged on the tubes and tighten the thumb screw on each foot securely. If installing on soft soil it maybe necessary to set the base foot on a concrete pad. 2.2.8. Adjust the final height of the platform by adjusting legs,one at a time, by loosening the outer set screws in the platform corner pockets. Using a level,adjust the platform height and re-tighten. 2.2.9. Once the final height has been adjusted,tighten the second, lower set screw in each platform corner pocket. 2.2.10. To allow access to the lowermost hole in the platform post,the support tubes must not extend more than 1/2"above the platform corner pockets.Trim the support tubes as needed before installing plugs. 2.2.11. Insert a plug into the top of each-support tubes. Use a rubber mallet or similar tool as needed (FIG.2.5). 2.2.12. Ensure all set screws are tightened securely.. 2.3. CONNECT TWO PLATFORMS TOGETHER 2.3.1. Assemble the first platform as described in the previous steps except on the side where the second platform will connect, install two.PPPC(CONNECTOR—PLATFORM TO PLATFORM) before installing feet onto the support tubes. 2.3.2. Make sure the platform connector set screws are oriented outward so they will be accessible. �► Any two platforms of the same width can be connected. However,two 5'x 4' platforms are usually connected to make a turn back platform. . 2-3.3. Slide the platform connectors up until they contact the bottom of the platform and tighten the set screws securely(FIG.2.6). 2.3.4. Install a support tube stub into the open pocket in each connector until the bottom of the stub is flush with the bottom of the connector and.tighten the set screws securely. 2.3.5. Install a-plug in the top of each support tube stub. 2.3.6. Assemble the second platform as described in the previous section except only install support tubes,plugs,.and feet on the opposite side of where the platforms will connect (FIG.2.7). 2.3.7. Lift the second platform and slide the open corner pockets over the support tube stubs extending up from the platform connectors.Tighten the set screws in the platform corner pockets securely. 2.3.8. Adjust the platform heights and level as needed. A Make sure all the set screws in both the platform corner pockets and the platform connectors are tightened securely before proceeding with the installation. Page 14 of 74 FIRST PLATFORM PLUG .

There are two options for 450 Angle Platform handrails,Two-Line and Vertical Pickets. The platform includes the handrail components needed for the option ordered. Platform handrails are shown for clarity of how to orient platforms in various configurations.It is strongly suggested that all platforms and ramps be installed before installing handrails(see'HANDRAILS'section). 2.4.2. Set platform on one of the sides where the ramp will attach and install legs and feet and adjust height as described previously in this section.The two legs on the short side must be.installed in the orientation shown(FIG.2.8) Use"low profile foot for platform heights under 4". �- It is sometimes helpful to lay platform on its side when inserting the legs.

Install ramps on both sides of the platform where there are no curbs. Refer to Section 3.2 for installing ramps on platforms and Section 4 for installing ramp handrails. 2.5. 8'X 5'TURN BACK PLATFORM This platform is used to create a turn back(or switchback) instead of connecting two 5'x 4' platforms. It includes two standard 5'platform handrails and handrails for the 8'side with a,curb. 2.5.1. Install the support tubes and feet as described in the'INSTALL SUPPORT TUBES AND FEET,THEN ADJUST PLATFORM HEIGHT'section. Page 16 of 74 2.6 INSTALL UNIVERSAL ANGLE BRACE-PLATFORMS For added stability,any platform with a walking surface over 36"high requires bracing.The PUA (PATHWAY!AN' GLE BRACE)is used for surfaces 36"up to 72".Walking surfaces 72"and higher requires cross braces in addition to the angle braces, 2.6-1. Angle braces come in pairs. Use four pairs per,platform (one pair per support tube, or side)or six pairs when two,platforms are:connected. 2.6.2.! Use'two,brace bands to secure the ends of the two angle braces nearest the twist to the support tube using a 5/16"bolt,flat washer,and put(FIG.2.9)., 2.6-3.- Opposite ends of the braces are attached to the bottom of the platform side rail at 90*to each other using a 1/4"x V long self-drilling screw(FIG.:2.9). W4"SELF. ILL DRILLING SCREW ANGLE BRACE • SUPPORT TUBE BRACE BAD- 16"CARRIAGE BOLT NUT&WASHER FIG. 2.9 2.7. INSTALL UNIVERSAL CROSS BRACE 2.7.1. Install UNIVERSAL CROSS BRACES on all support tubes when the walking surface-is 72"or more above the ground.Cross braces are normally installed on all four sides (FIG.2.10) unless two platforms are connected. 2.7-2. Ensure that all cross braces are secured before using platform. FIG. 2.1W CROSS BRACE ASSEMBLY Page 17 of 74 3. RAMPS 3.1. CONNECT RAMP SECTIONS 3.1.1. Place the walking surface side of the ramp sections face down,onto cardboard or lawn so that the ramp is not damaged (scratched or dented): When installing a single ramp section, skip to 'INSTALL A SINGLE RAMP RUN TO AN EXISTING STRUCTURE'. 3.1.2. Butt the sections together end-to-end and ensure there is no gap,then position the two center saddle brackets,included in the PRRC(CONNECTOR—RAMP TO RAMP), over the threaded inserts at the end of each ramp section(FIG.3.1). 3.1.3. One edge of the center:saddle bracket will slide into the groove of the ramp sections. To create a run, ramp sections are connected using two interchangeable center saddle brackets per joint.The center saddle brackets are also where the handrails and ramp legs are attached. 5116"-18 X 1-1/2"LONG HEX BOLT 5116"FLAT WASHER ENTER SADDLE BRACKET 5116!-18 THREADED INSERT 5/16"-18 X 1-1/2"LONG HEX SOLT o 5/16"FLAT WASHER RAMP HANDRAIL END BRACKET RAMP CONNECTION -- ------ 5/11WAS THREADED INSERT END OF RAMP OR RAMP RUN FIG. 3.1 FIG 3,2 (BOTTOM VIEW) (BOTTOM VIEW) 3.1.4.- Attach the center saddle brackets using four each 5/16"-18 x 1-1/2"bolts and 5/16" washers per bracket.Tighten all eight bolts(four each per center saddle bracket). Although a system can have multiple ramps per run,'it is recommended that a maximum of three ramp sections at,a time be joined in this manner. 3.1.5. If necessary,install optional PRST(RAMP SUPPORT—TOP)at this time(see 'OPTIONAL EQUIPMENT'section). 3.1.6. Locate PRHBPR(RAMP HANDRAIL END BRACKET PAIR). Install four end brackets (these will be used to attach handrails in a later step).Use one end bracket at each outside corner of the ramp"or ramp run using,one 5/16"X 1.-1/2"bolt and washer into the threaded-insert closest to the end of the ramp(FIG. 3.2). 3.1.7. Turn the joined ramps to their upright position,being careful not to damage the threaded studs. Page 18 of 74 3.2. INSTALL RAMPS ON PLATFORMS 3.2.1. The following will address attaching a ramp or ramp run to a platform. If the ramp " needs to be angled with respect to the platform or is going to be attached to an existing porch,skip to'ANGLE RAMPS WITH RESPECT TO PLATFORMS, PORCHES,OR DECKS'in this section. 3.2.2. Ramps are most commonly located toward either the left or right side of the platform or centered but can be placed in any location on a platform side except when using a 'VERTICAL PICKET CLOSURE'(outlined in SECTION 5).When the ramp is located toward the side of a platform,the ramp handrail post should be positioned 1-1/2" (minimum)to 2"from the inside of the platform post.When using other locations,a second closure(Single-Line,Two-Line or Horizontal Picket)-must be ordered to connect the ramp and platform handrails.When centering ramps using a Vertical,'' -Picket Closure additional components are'needed.The additional components will come.with the closure if specified at the time of order.The closure can also be converted in the field by ordering a second set of hardware. 3.2.3. Locate a PRHP(RAMP HANGER PAIR)and install the two hangers in the platform side rail where the ramp will be attached. 3.2.4. Hold the hanger perpendicular(approximately)to the platform side rail'then bring the hanger upward until it is against the side rail lip. Rotate the hanger and continue pushing upward in such a manner that the"hook"at the top of the hanger goes behind and catches on the lip in the top of the platform side rail and the hanger sits on the ledge at the bottom (FIG.3.3). 3:2.5. Set the ramp on the hangers.The hangers should be positioned as close as possible to the ramp side rails.The procedure is the same at both the top and bottom of ramp runs which end at a platform unless a transition plate is used (FIG.3.4). A Do not attempt to walk on ramps until installation is complete. ` -HOOK"IN TOP HANGER LIP IN PLATFORM__,1_�_ SIDE RAIL / I -RAMP RAMP RAMP HANGER- I i AFTER ROTATING HANGER INTO PLACE PLATFORM ENO VIEW OF PLATFORM WITH PLATFORM CORNER POCKET&LEG HIDDEN PLATFJ ORM RAMP HANGER—i— (21RAMP) 9 I FIG. 3.3 FIG. 3.4 (TOP VIEW) (BOTTOM VIEW) !

Level the Support Leg Bracket using a bubble level or similar tool,then torque the 5/16"-18 nylon insert locknuts to 20 ft.-lbs. 3.3.4.- Locate the appropriate PRLxxPR(RAMP LEG PAIR where"xx" denotes the leg length) for the location. Place a polymer foot under the Support Leg Bracket with the foot extending under the ramp,then insert a 1-1/2"square Support Leg through the Support Leg Bracket into the,foot. Loosen the 3/8"-16 headless socket setscrews and the foot thumb screw if needed to fully engage the Support Leg in the foot(FIG. 3.6). If installing on soft soil it maybe necessary to set the foot on a concrete pad. 1-1/2"SQUARE TUBE PLUG i 1-112"SQUARE SUPPORT LEG FIG. 3.6 e .0 3/8"-16 HEADLESS SOCKET p SET SCREW(2/13RACKET) POLYMER FOOT FOOT THUMB SCREW Page 20 of 74 3.3.5. 1 After the Support Leg is fully engaged in the foot,tighten the 3/8"-16 headless socket setscrews to 15 ft.-Ibs.(FIG 3.6) A Do not attempt to walk on the ramps until all Support Leg set screws have been tightened as specified. 3.3.6. Tighten the foot thumb screw and insert 1-1/2"square plug into the top of the Support Leg(FIG.3.6). 3.3.7. Repeat the above procedure at all locations where ramps connect and at the end's of a ramp or ramp run if a PRST—Ramp Support Top is used. In situations where the lower end of a ramp or ramp run is too close to the ground to install normal feet and feet are needed due to ground or other conditions,special welded low profile feet(part no. PRLPRLP).are available (FIG 3.7). 3.3.8. Remove the 5/16"-18 nylon insert locknuts and 5/16"flat washers attaching the ramp handrail post(if already installed), position the low profile foot so the foot is oriented under the ramp and the channel leg wraps around the ramp post. Reinstlall the locknuts and flat washers,adjust height as described below then tighten fasteners securely. Repeat on the opposite side(FIG.3.7).

Adjust the ramp legs one at a time. �- ADA guidelines call for a maximum slope of 1:12(approximately 50)and this is the ideal slope for the PATHWAY 3G system. However,the ramps can be installed from 1:14 to 1:8(approximately 4'to 7'). Do not attempt to install'the ramps outside this range. l �- NOTE if the ramp is installed at the maximum angle(approximately 77) longer legs may be required. 3.3.9.1. Raise the ramp sections(at the center saddle bracket)to take any sag out of the ramp run,then tighten the two locknuts in each leg. l Adjusting sections can be accomplished by having someone sight down the, ramp while another person adjusts the ramp height. It's important-to ensure that the ramp sections are parallel to each other. if they are not, it may be difficult to install the Handrails(FIG.3.8). 3.3.9.2. Insert a plug into the top of each leg(FIG.3.6). i Page 21 of 74 3.3.10. Ensure that all bolts are tight and the ramp sections are aligned parallel to one another.

The opposite end of the angle brace is attached to the bottom of the ramp(near the center of the tread at the end of the ramp) using a 1/4"x 1"long self-drilling screw. 3.3.12. Ensure that all angle braces are secured before using the ramp. A Walking surfaces over 72"or more above the ground require UNIVERSAL CROSS BRACES in addition to the angle braces(see'INSTALL UNIVERSAL CROSS BRACE' section).The process for installing cross braces to ramp legs and platform support tubes is the same.. Page 22 of 74 3.4. INSTALL GROUND TRANSITION RAMP 3.4.1. 1 The PRGT(RAMP GROUND TRANSITION)consists of two sections that need to be i installed into the ramp and connected together. I.& The PRGT(RAMP GROUND TRANSITION)is only designed to transition from the { lowest ramp-in the run to the ground. Do NOT USE in any other location. 3.4.2. 1 Lift the lowest end of the ramp/ramp run and bring the upper.section PRGT into.the ramp end tread until the"hook" is engaged FIG.3.10),then rotate into place(FIG: 3.11)and set back on the ground.

Like the ramp and platform handrails, they are available in Two-Line,Single-Line,Vertical Pickets and Horizontal Pickets.As a standard,the closures come with components which require the ramp to be mounted to one side or the other of a platform but the ramp can also be centered or mounted in any location on a platform side except when using the Vertical Picket closure(refer to Section 5.3).When centering the ramp or mounting in a location other than the side,a second Two-Line,Single-Line or Horizontal Picket closure must be ordered and is installed in the same manner as described.below.When-mounting to the side,the ramp handrail post should be positioned 1-1/2" (minimum)to 2"from the inside of the platform post. For a Single Line closure the steps in this section complete the installation. 5.1. If installing a closure on a platform in the "straight"configuration,the 2"x 2"angle post will already be in place.Skip to 5.1.4 5.2. If installing on a platform in the"turn"configuration,install the 2"x 2"angle post not attached to a platform handrail in the open platform corner pocket.Align the bottom of the post with the bottom of the corner pocket and tighten the set screws securely(FIG.5.1). Refer to Section 4.5 for addition details on securing the post. 5.3. Install the angle cap on top of the post.Glue in place using construction adhesive as needed. 5.4. First install the top rail,the rail connecting the ramp handrail to the platform post. This procedure is the same regardless of the style of closure. Insert an adjustable elbow in the ramp handrail. Loosen the elbow assembly screws and position the round portion of the adjustable elbow so it is aligned with the upper hole in the angle post and the face is parallel to the post.

SECURE RAMPS TO PLATFORMS 6.1.1. Once positioning of all ramps and platforms,and installation of all handrails, connectors,and end loops are complete,you will need to secure ramps to platforms with Ramp End Clips(included in.PRHP-RAMP HANGER PAIR). A Use two Ramp End Clips at all locations where ramps meet platforms. 6.1.2. Position each Ramp End Clip with the hole pointing up and oriented as shown(FIG. 6.1),then insert the short end of the Ramp End Clip into small gap between the ramp and the platform in the area where the ramp side rail overlaps the ramp end tread (FIG.6.1). 6.1.3. Before the Ramp End Clip contacts the ramp side rail,rotate the Ramp End Clip so;the ,.short end extends into the recess under the ramp end tread.(FIG.6.1). . 6.1.4. Use:the hole in the Ramp End Clip as a template to drill 1/8" pilot hole in the platform side rail,then use the 1/4"x V long self-drilling screws to secure the Ramp End Cli p to the platform side rail (FIG.6.2) 6.1.5.

If using the auger style tie downs(soil and asphalt), install the auger into the ground in line with the brace band. Install as close to vertical as possible, 10`angle maximum. Use a 1/2"steel rod (or similar item)through the eye of the auger anchor to turn the auger anchor into the ground. Keep turning the auger until only the eye is exposed. 7.7.5. If using concrete anchors,install per the manufacturer's instructions then install a 5/16"eyebolt. 7.7.6. Place the other end of the wire rope either through the eye of the auger anchor or through the eyebolt in the concrete anchor and secure the wire rope together using the supplied 3/16"wire rope clamps. A Make sure that the wire rope has been pulled taut and all slack has been removed prior to securing it with the wire rope clamps. 7.7.7. Cut the excess wire rope as required using a cable cutter or other appropriate tool. Wrap the cut ends with vinyl tape(or equivalent)to keep the wire rope from fraying. 7.7.8. Repeat for all support tubes. 7.7.9. If used on a single ramp, install tie downs approximately in the center using eyebolts (FIG.7.10). 7.7.10. If there is are support tubes in the ramp run,the same method as described above for platforms can be used.Otherwise,drill a 5/16"hole below the tread surface (approximately 3/4"above the bottom of the side rail)and between the ribs underneath the treads in each of the side rails at the desired location. Page 68 of 74 Install one of the 5/16"eyebolts and secure to the ramp using one 5/16"flat washer and one 5/16"nut in each hole(FIG.7.12). 7.7.11.'

Caution should be used at all times.Proper maintenance and upkeep to the ramp surface is vital. 8.1.2. Use tamp only with a qualified helper. 8.1.3. Always use your mobility device's lap belt. 8.1.4. It is important that you refer to your equipment's Owner Guide for the proper degree of incline/decline and chair direction before at-tempting ramp use. Never exceed its recommendations. 8.1.5. Periodically check the ramp for damage and tighten any loose fasteners to ensure safety. 8.1.6. At all times,keep the ramp clear of dirt,leaves,and other debris that may accumulate on the surface.Simply sweeping the-ramp or using a garden hose will usually suffice,but,if needed,a damp cloth or soft brush with soap and water can be used(avoid use of alkaline detergents). 8.1.7. If ramp surface is covered with ice and/or snow,the recommended procedure is to remove ice and/or snow before use.Snow accumulation should be shoveled and the tread surface swept clean. Magnesium Chloride may be used to melt snow or ice accumulation on the e ramp;however,after the snow and/or ice threat has cleared, be sure to clean the tread surface with soap and water (avoiding alkaloid detergents)to remove Magnesium Chloride residue.See DE- ICING below for additional information. 8.1.8. Do not play on or near ramp. 8.1.9. Do not use,handrails or ramp to support planters,decorations,etc. 8.1.10. RAMP SURFACE MAY BECOME SLIPPERY WHEN WET, USE EXTRA CAUTION WHEN THE RAMP SURFACE IS WET. 8.1.11. If any part of the ramp is damaged or loose,DO NOT USE UNTIL REPAIRS ARE MADE BY A CERTIFIED-INSTALLER OR OTHER QUALIFIED PERSON. Page 72 of 74 9.
