The TBD22 diagonal truss brace offers a time-saving substitute for hat channel or C-stud diagonal bracing that helps meet the prescriptive recommendations of CFSBCSI. The TBD22 travels in a box like a flat strap (160 feet per carton), and is formed into an A-shape as it is pulled from the carton to provide rigidity and prevent sagging between trusses during installation. As it is fastened to the trusses the brace flattens, allowing sheathing to be installed over it, saving the time typically needed to remove bracing prior to applying the sheathing or decking.

Material:27 mil (22 ga)

Finish: Galvanized

Installation:

• Use all specified fasteners; see General Notes
• Strap does not have holes for fasteners. Screws shall be installed in the dimpled areas and placed to maintain a minimum of 1/4" strap edge distance and a minimum of 1/2" center to center distance.
• TBD22 strap span diagonally at approximately 45 degrees.
• Strap shall not be slack, but tight and ready to engage in tension.
• To resist construction forces, diagonal X-bracing is required at each end and every 10 truss spaces (20' max.). Refer to SBCA CFS-BCSI for additional information.
• At the end of the TBD22 braces, trusses shall be laterally restrained to resist out-of-plane forces.
• Bracing locations shown in the drawing are recommendations for temporary bracing only. Installation of TBD22 for permanent bracing shall be by the Building Designer or Engineer of Record.
