The new DG fire wall hanger series from Simpson Strong-Tie, an industry leader in engineered structural connectors and fasteners, is ideal for Type III multi-family, multi-level building construction and easily installs on a two-hour wood stud fire wall during framing – before the drywall is in place. The new series includes three models of top-flange hangers that connect floor joists to the wood wall and feature enough space for two layers of 5/8-inch drywall to be installed later. The completed fire wall assembly remains continuous from floor to floor. All three fire wall hangers have been tested according to ASTM E814 standards to verify that the hangers do not reduce the two-hour assembly rating, and therefore each of the DG hangers received F (flame) and T (temperature) ratings for use on either or both sides of a wall.
