B. Light Gauge Framing* — Slip clips shall consist of min 20 gauge galv steel and have a min width of 1-1/2 in. (38 mm).  The slip clips have a formed channel that is designed to accommodate the return flange on the steel stud (Item 2C), this channel will vary with the size of steel stud that is used.  They are attached to the inside bottom leg of the ceiling runner (Item 2A) with 2 - No. 8 by ½ in. (12.7 mm) long steel self-drilling framing screws and engage the return flange of the stud.  

FIRE TRAK CORP — Posi Klips

C. Studs — Steel studs to be min 2-1/2 in. (64 mm) wide and as specified in the individual Wall and Partition Design in the UL Fire Resistance Directory. Studs cut 4 in. (102 mm) less in length than the assembly height with bottom nesting in and resting on floor runner and with top nesting in ceiling runner without attachment. Stud spacing not to exceed 24 in. (610 mm) OC.
D. Gypsum Board* — Gypsum board sheets installed and attached to studs and runners as specified in the individual Wall and Partition Design in the UL Fire Resistance Directory, except that a nominal 3-1/2 in. (89 mm) gap shall be maintained between top of the gypsum board and the bottom flange of the deflection track. Top row of screws shall be installed into the studs 13-1/2 in. (343 mm) below the top edge of the gypsum board sheets.
E. Bracing — (Not shown) Bracing as specified in the individual Wall and Partition Design in the UL Fire Resistance Directory.

The hourly assembly rating of the joint is equal to the fire rating of the wall.

Firestop Configuration A and A1
3. Joint System- — Max separation between bottom flange of the deflection track and top of gypsum board (at the time of installation of the joint system) is 1 in. (25 mm). The joint system is designed to accommodate a max 100 percent compression or extension from its installed width. The joint system consists of spray applied fire resistive material (Item 3A), and wall cladding (Item 3B), as follows:
A. Wall Cladding — Strips of the gypsum board material attached to the deflection track. The number of layers, board type and thickness and fastener type shall be as specified for the gypsum board in the individual Wall and Partition Design in the UL Fire Resistance Directory. Fasteners shall be max spaced 3 in. (76 mm) OC. The top of the wall cladding shall be flush with the valleys of the steel floor units and overlap the gypsum board 7 in. (178 mm) irectory. Fasteners shall be max spaced 3 in. (76 mm) OC. The top of the wall cladding shall be flush with the valleys of the steel floor units and overlap the gypsum board 7 in. (178 mm).
B. Flute Fill — The batt insulation and fill material are to be installed as specified in the Joint Systems in the table below:
