2. Wall Assembly — The 1 or 2 hr fire rated gypsum board/stud wall assembly shall be constructed of the materials and in the manner described in the individual U400, V400 or W400 Series Wall and Partition Design in the UL Fire Resistance Directory and shall include the following construction features:

A. Steel Floor And Ceiling Runners — Channel shaped runner with width to accommodate studs, legs of min 2-1/2 in. (64 mm), and fabricated from min 20 MSG galv steel. Ceiling runner installed below and parallel to steel beam. Floor runners of wall assembly shall consist of min No. 25 ga galv steel channels sized to accommodate the steel studs. Floor runner to be provided with min 1-1/4 in. (32mm) flanges. Ceiling runner to be attached to steel attachment clips with steel fasteners spaced a max of 16 in. (406 mm) O.C. Floor runner to be attached to floor with steel fasteners spaced a max of 24 in. (610 mm) O.C.

Light Gauge Framing* — Slotted Ceiling Runner - As an alternative to the ceiling runner in Item 2A, slotted ceiling runner to consist of galv steel channel with slotted flanges sized to accommodate steel studs (Item 2B). Slotted ceiling runner to be provided with minimum 2-1/2 in. (64 mm) flanges. Slotted ceiling runner secured to floor with steel concrete anchors spaced max 12 in. (305 mm) OC.

See Light Gauge Framing (XHLI) Category for names of Classified Companies.

B. Steel Attachment Clips — Z-shaped clips formed from min 1 in. (25 mm) wide strips of min 20 ga galv steel. Clips sized to extend through the thickness of the spray-applied fire resistive material on the bottom flange of the steel beam with min 1-1/2 in. (38 mm) long upper and lower legs. Legs of clips fastened to bottom of beam (prior to application of spray-applied fire-resistive materials) and top of ceiling runner with steel fasteners or welds. Clips spaced max 16 in. (406 mm) OC.

C. Batts and Blankets* (Not Shown) — Faced or unfaced glass fiber insulation or mineral wool insulation completely filling stud cavity. Insulation shall meet the specifications described in the individual Wall and Partition Design.
