Uark®6etrich CT Cavity Shaft dl System
ClarkDietrich CT Cavity Shaftwall Studs are high-performance members engineered to maintain
shaftwall integrity. CT Studs are designed for use with 1" thick gypsum 24" wide liner panels.
Gypsum liner panels are inserted into the "T" portion of the stud and are friction fit. The system is
finished with fire rated gypsum board to complete and achieve the designated fire rating.
ClarkDietrich J-Tabbed Track is used at the floor and ceiling in shaftwall assemblies. CT studs and
gypsum shaftiiner panels are friction fit between the top and bottom J-Tabbed Track. J-Tabbed
Tracks have unequal legs. The longer leg (available in 2-1/4" and 3") is installed on the shaft side
providing a backstop for easy installation of the liner panel. Three-inch leg track is typically used
as jamb struts around closure details, including duct and door openings, abutments and
intersections.

Sound Control
The Shaftwall / Stairwall assemblies and their components mentioned in this A ER report have been tested in accordance with ASTiM
E90 (90) and ASTM E413 (87). The shaftwall assemblies were evaluated for sound transmission loss values. These values are only
valid if the assemblies are constructed as noted in the test reports. When the assemblies are installed in the same manner as noted
in the test reports, the assembly will have a minimum STC (Sound Transmission Class) rating of 50.
General Product Usage and U nitations
1. Shaftwall assemblies are limited to interior applications only.
2. The ClarkMetrichT"' Shaftwall/Stairwall systems should be installed according to AISI's Standard for Cold -Formed Steel Framing -
General Provisions and to the manufacturer's written instructions unless more stringent requirements are required.
3. The ClarMetrichT" Shaftwall/Stairwall systems are designed to enclose stairwells, corridors, elevator shafts, mechanical
components, and other vertical shafts.
4. Non -load bearing Shaftwall / Stairwall assemblies are limited to fire -resistance only. Structural and other requirements shall be in
accordance with pertinent building code and manufacturer's requirements.
5. Do not install in areas which will be adjacent to occupancies of unusually high moisture conditions.
6. C-T Studs cannot be spliced. They must be installed full length and one piece. J-runners when not attached to the structure shall
not be spliced. Do not attach the J-runners to the C-T Studs unless noted otherwise by the manufacturer's installation procedures.
7. To prevent air movement, the partition perimeters, as well as all penetrations, should be effectively sealed with non -hardening
sealant.
8. Applications that require the use of joint treatment shall follow the manufactures usage instructions to ensure the finishing of the
joint layers is done within the temperature requirements of the product. Reference Section 715 of the 2012 International Building
Code.
9. Not recommended for use as unlined HVAC supply shafts or ducts.
' 10. Hollow cavities must be fire stopped at each floor.
11. All fire resistive assemblies shall be built in accordance with the applicable published UL designs, or as a otherwise described
within this report.

General Product Usage and Limitations
11. Control joints should be located in way that limits the maximum continuous partition length to 30 feet. The partition control joints
should coincide with the building structure where possible. .
12. All Shaftwall and Stairwall members shall be simple span members with no intermediate supports.
13. Gypsum panels may be cut and stacked with joints occurring within the top and bottom third points of the wall. Joints in adjacent
panels shall be alternately staggered to prevent a continuous horizontal joint. The gypsum panels must engage a minimum of two (2)
tabs.
