Drift Strut Connector
From Simpson Strong-Tie
Simpson Strong-Tie introduces the easy-to-install DSSCB bypass framing drift strut connector to support cold-formed steel bypass framing while accommodating horizontal building drift.
The patent-pending DSSCB connector is uniquely formed to friction fit within 13/16" or 1 5/8" commodity strut channels currently in the market place. To install, simply slide the clip into the strut channel and twist.
As a dual-function connector with pre-punched slots and round holes for slide-clip and fixed-clip applications, the DSSCB allows contractors to install finished panels while working from the top of the slab without the need to predrill or to preinstall anchors for each clip. Made from 12-gauge steel and tested in accordance with ICC-ES AC261, the DSSCB is available in 3 1/2" (DSSCB43.5), 6" (DSSCB46) and 8" (DSSCB48) lengths. In addition, an optional DSHS drift stopper is sold separately to make framing easier to adjust and lock into place as required.
The pre-punched slots provide a full 1" of upward and downward deflection. Precision-manufactured #14 shouldered screws, included with the DSSCB, are designed to prevent overdriving for proper clip functionality, while slot markers ensure perfectly centered screw placement.
Depending on the application and the designer specifications, struts can be mechanically anchored, welded or cast in place. Design values for the DSSCB and strut channel have been provided in easy-to-use load tables and are based on assembly testing to mitigate risk for designers.
