2 ICC-ES Evaluation Report ESR-1464 Reissued January 2018 This report is subject to renewal January (800) (562) A Subsidiary of the International Code Council DIVISION: METALS Section: Cold-Formed Metal Framing DIVISION: FINISHES Section: Non-Structural Metal Stud Framing REPORT HOLDER: CLARKDIETRICH BUILDING SYSTEMS 9050 CENTRE POINTE DRIVE, SUITE 400 WEST CHESTER, OHIO (513) EVALUATION SUBJECT: TRAKLOC NONLOAD-BEARING WALL STUD FRAMING SYSTEM 1.0 EVALUATION SCOPE Compliance with the following codes: 2015 and 2012 International Building Code (IBC) Property evaluated: Structural 2.0 USES The TRAKLOC nonload-bearing wall steel framing system is used for framing of interior nonload-bearing walls. 3.0 DESCRIPTION 3.1 General: The TRAKLOC nonload-bearing wall steel framing system is constructed from the TRAKLOC studs and tracks which are available in four depths and four material thicknesses as noted in Table 2. The studs and tracks have a twist and lock system that permits stud installation into the top and bottom tracks without the use of fasteners. The TRAKLOC studs are available as single-unit fixed-length studs and as two-part adjustable-length studs TRAKLOC Fixed Length Stud: The TRAKLOC Fixed Length Stud (TLF) is not adjustable and is a single piece component. It is swaged at each end to interlock with TRAKLOC Track. The TLF is provided to job specific fixed lengths. The single-unit fixed-length studs (TLF) have the designation xxxtlfxxx-xx TRAKLOC Adjustable Stud: The TRAKLOC Adjustable Stud (TLA) is a two-piece stud that is adjustable in length at the top of the stud. It is used where small allowances for live-load and/or seismic-induced inter-floor vertical deflection is not needed. The adjustable-length studs are made up of two parts, the outer stud base (TSO) and the short inner stud TRAKLOC extension piece (TSE). See Figure 3. The TSE is fitted into the TSO, allowing the length of the TRAKLOC stud to be adjusted in the field. The TRAKLOC Adjustable Studs (TLA) have the designation xxxtlaxxx-xx TRAKLOC Deflection Stud: The TRAKLOC Deflection Stud (TLD) is a two-piece stud that is adjustable in length to accommodate small allowances for live-load and/or seismic-induced inter-floor vertical deflection. The short inner stud TRAKLOC extension insert (TSE) has slots cut out of the flanges to allow the drywall screw to penetrate through the drywall and the outer portion of the stud (TSO) while passing through the slot. The slot allows the drywall to be attached while still allowing for deflection at the head-of-wall joint. See Figure 3. The TSE is fitted into the TSO, allowing the length of the TRAKLOC stud to be adjusted in the field. The TRAKLOC Deflection Studs (TLD) have the designation xxxtldxxx-xx TRAKLOC Extension Insert: The TRAKLOC extension insert (TSE) is used with the TLA and TLD to allow for small amounts of vertical deflection. It has a base metal thickness of 33 mils. The minimum overall length of the TSE is 12 inches (305 mm) with a required minimum overlap length of 8 inches (204 mm) and a maximum unlapped length of 4 inches (102 mm). It is manufactured without web punch-outs, and with and without flange punch-outs. The flange punch-outs, when present, are 3 / 4 -inch by 3.0 inch (19 mm by 76 mm). The TSE without flange punch-outs is used with the TSO for the adjustable length studs (TLA). The TSE with flange punch-outs is used with the TSO for the deflection stud (TLD). See Figure TRAKLOC Elevator Stud: The TRAKLOC Elevator Stud (TLE) is comprised of two approximately equal length TSO & TSE parts of like thicknesses and is supplied in collapsed or retracted position to accommodate transport in a building elevator. It is then extended (telescoped) to the required fully extended length at the point of installation. The minimum overlap length for the elevator studs (TLE) is 11 inches (280 mm). The TSE and TSO components for use with the elevator stud are manufactured with web punch-outs. Each component is ICC-ES Evaluation Reports are not to be construed as representing aesthetics or any other attributes not specifically addressed, nor are they to be construed as an endorsement of the subject of the report or a recommendation for its use.

The TRAKLOC Elevator Studs (TLE) have the designation xxxtlexxx-xx TRAKLOC Track: The TRAKLOC Track has a V-groove rolled into the flanges of the track to match the swaged ends of the TRAKLOC stud and dimples pressed into the center of the web. The TRAKLOC Track is typically provided in 10 foot (3048 mm) lengths. Custom lengths are available. The tracks are channel-shaped with an inward ridge to twist and lock the studs to the track and have the designation xxxttsxxx-xx. See Figure 1 for stud and track configurations. See Figure 2 for punch-out configurations TRAKLOC Punch-outs: The TLF fixed length stud and the TSO for the adjustable length studs (TLA) and the deflection studs (TLD) are manufactured with web punchouts. The punch-outs are 3 / 4 -inch by 4.0 inches (19 mm by 102 mm) for TSOs with web depth of less than 3 inches (76 mm). For all other TSO web depths the punch-outs are 1 1 / 2 -inches by 4.0 inches (38 mm by 102 mm). Punch-outs are spaced a minimum of 24 inches (610 mm) on center along the centerline of the TSO, with a minimum distance of 10 inches (254 mm) from the end of the member to the near edge of the punch-out. 3.2 Material: Steel: The 24 mil studs and tracks are formed from coils of steel complying with ASTM A1003, NS57. All other studs and tracks are formed from coils of steel complying with ASTM A1003, NS33. The uncoated minimum base-metal thickness is specified in Table 2. The coating on the steel is a metallic coating conforming to ASTM A653/A653M with a minimum G40 (Z120) coating Gypsum Wallboard: Gypsum wallboard must be a minimum of 5 / 8 -inch (15.9 mm) thick and Type X, complying with ASTM C1396 and manufactured by of the following companies: American Gypsum; CertainTeed; Georgia Pacific; Continental; National Gypsum; or United States Gypsum Fasteners: Fasteners attaching the gypsum wallboard to the studs and tracks must be No. 6, Type S, fine thread drywall bugle head screws conforming to ASTM C DESIGN AND INSTALLATION 4.1 Design: The allowable values and tabulated limiting heights for both non-composite and composite designs are for use with the Allowable Strength Design (ASD) Section Properties: The properties in Tables 3, 4, and 5 have been determined in accordance with the applicable edition of the North American Specification for Design of Cold-Formed Steel Structural Members (AISI S100) Non-Composite: The limiting wall heights provided in Table 6, 7, 8, 9, 10, 11, 12, and 13 were determined by an all steel based design using the section properties in Tables 3 and 4 for simple spans Composite: The limiting wall heights provided in Tables 14, 15, and 16 were determined based on the composite action between the gypsum board and the steel studs. 4.2 Installation: Installation of the TRAKLOC nonload-bearing wall steel framing system must be in accordance with the applicable code, the approved construction documents and this report.
