SYNOPSIS OF CHANGES IN 15C
STATE OF FLORIDA
1. I -BEAM CLAMP THAT PIVOTS - TOP OF FRAME ONLY The State of Florida now requires that the strap be attached to the I-beam
by a beam clamp that has a swivel attachment. This eliminates the sharp edge of the frame cutting into the strap and the
possibility of stressing one edge of the strap by misaligning the anchor with the attachment point to the I-beam.
2. GALVANIZED STRAPS .60 OUNCES EACH SIDE OR NOMINAL G115 Florida now requires that all strapping have extra
galvanization to protect from the elements. All strapping must be marked with the "G115" coating, and Tie Down strap will
indicate "QUAD COAT G-120." The ASTM 3953-91 must still be referenced on the strap to indicate conformity to the HUD Code,
and the G115 will indicate the extra coating. All strap must be marked every 12" to 15".
3. ALL ANCHORS GALVANIZED All ground anchors, concrete anchors, patio anchors, etc. - must be hot dip galvanized.
4. MINIMUM STABILIZER PLATES 180 SQUARE INCHES, GALVANIZED The small 12" stabilizer plate is no longer certified in Florida.
All stabilizer plates under the new regulations must have a minimum 180 square inches of surface and must be galvanized. Tie
Down manufactures the 17.5 inch plate that is galvanized to meet Florida requirements.
5. RADIUS CLIP PROTECTION The State of Florida no longer allows the strap to wrap the I-beam. Because strap must be protected
from contact with sharp edges, the strap must now be attached to the I-beam by means of a swivel connector with a radius
clip (rolled edge). The strap must also be factory attached to the connecting swivel bracket. Field attached crimp seals are no
longer allowed for use on straps used to attach to frame connectors or hooks.
6. SIDEWALLVERTICAUFRAME TIES 514" 0/C The maximum distance between sidewall vertical/frame ties is now 5'4" on center.
7. CENTERLINE TIES WITHIN TWO FEET EACH END Every new and used multi -section home must include a centerline anchor
installed within two feet of each end of each centerline (the home manufacturer may require additional anchors.
8A. LONGITUDINAL ANCHORS, TWO PER I -BEAM PER END As part of the new rules, every home must be installed with protection
from wind loads on the end of the home. The Florida rules require two anchors per I-beam per end. This means that a single
section will require four longitudinal anchors per end for a total of eight for the home. A double section home will require eight
anchors per end for a total of sixteen per home. As with all ground anchors, these must be hot dip galvanized and in
stalled with a galvanized stabilizer plate. Torque probe is required on longitudinal anchors.
8B. LONGITUDINAL STABILIZER DEVICES As an alternate to installing longitudinal anchors and stabilizer plates, the installer may
use other longitudinal stabilizing devices approved by the state, including Tie Down's LzSD (Longitudinal Stabilization Device).
The use of two USD systems on a single section home replaces all eight longitudinal anchors/stabilizer plates. Four LzSD
systems on a double section home, replaces sixteen anchors/stabilizers/frame tie connectors.
9. SOIL TEST While the soil test probe is not specifically addressed by 15C, the installer is required to A) test and record the
torque readings and install the correct ground anchor (48" or 60") or B) use a 60" galvanized anchor with stabilizer plate where
no testing is recorded.
10. INSTALLER PLAN FOR 1,000 PSF SOIL The installer must submit a foundation plan (as to the load bearing capacity of the soil)
to the building department at the time of application for the building permit. If the soil is not tested with a penetrometer, then
the plan submitted must assume 1000 PSF soil. The installer is required to use a pocket penetrometer to determine the PSF
NOTE:1000 PSF soil most commonly requires Type II, 60" anchors.
11. MINIMUM HEIGHT 18 INCHES The minimum pier height at the lowest part of the home shall be 18". This distance is measured
from the bottom of the frame (I-beam) to the ground or slab. Note: 3/4 of the home must be at the minimum 18", the balance of
the home cannot be lower than 12".
12. GROUND ANCHORS / FLORIDA ONLY For purposes of installation of manufactured/mobile homes in the State of Florida, there
will be two soil classifications:
Type I: This soil is described as "loose to medium dense sands, firm to stiff clays & silts, alluvial fill." It has a Blow Count (per
ASTM D1586) of 18 to 23, and a reading on the Torque Probe of 276 to 350 inch pounds. The Working load for an anchor in
Type I soil is 3,150 lbs. and the Ultimate load is 4,725 lbs. A 48" anchor is to be used in 4A soil classifications.
Type II: This soil is "very loose to medium dense sands, firm to stiff clays and silts, alluvial fill." The Blow Count for Type 11 soil
is 12 to 17, and the torque reading 175 to 275 inch pounds. The Working load is described as 4,000 lbs. and the Ultimate load
is 6 000 lbs. A 60" anchor must be used in 4B soil classifications.

Frame Tie to Anchor
If the angle of the frame tie connection is greater
than 500 (as Indicated by curved line illustration),
the frame tie must be attached to the.opposite "I"
beam frame member. 45° is the correct angle for this
installation.

Ground Level
A galvanized Stabilizer Plate of 180 sq.
in. must be installed on all anchor/frame
tie combinations.
Use a Soil Test Probe to match either Type
1, 48" or Type 2, 60".ground
anchor to soil conditions.
Frame Tie Attachment
1. All frame ties must be attached with a swivel
frame connector. Strap must be factory attached to
the connecting bracket.
2. Attach the swivel frame connector beam hook
to the top of the I-beam from either the front or
the back side. The curved or hook end of the beam
hook should be snug against the inside top I-beam
flange.
3. Attach the swivel connector to the underside of
the frame hook with a 1/2" grade 5 bolt and nut.
This allows the swivel connector to pivot and lock
onto the I-beam.
4. Pull strap past anchor head 10 to 12 inches.
Insert strap into slotted bolt. Tighten slotted ten-
sioning bolt 5 full turns minimum until all slack in
strap is removed (Correct anchor must be installed
as per ground anchor manufacturer's installation
instructions).
Anchor Stabilizer
All anchors must be properly stabilized to prevent lateral
movement of the home and to comply with federal and state
wind load requirements.

2. Soil Test Probe anchor location in order to match soil
class to ground anchor model.
3. Partially install anchor at a slight back angle allowing
14" to 16' to remain above ground level.
4. Utilizing oversize hammer, vertically install stabilizer
plate, nesting stabilizer plate between anchor and frame.
5. Fully install anchor to ground level. Tighten strap,
pulling anchor until anchor rod is pre -tensioned against
stabilizer plate.
Strap Attachment
The strap must be attached to the 1-beam by using a beam
clamp with a swivel connecting bracket. Strap must also be
factory attached to the connecting bracket. In field crimp
seals are no longer allowed for use on strap to attach to
frame connectors or hooks.

and the strap is adequately
tensioned.
2. Insert the strap end into
the slot in bolt until flush
with opposite side of bolt.
4. Hold the bolt under
