Simpson Strong-Tie 12 Gauge 3-1/2 x 18 In. Joist G90 Coating DGF Fire Wall Hanger

The DGF fire wall hanger is ideal for multi-family. multilevel building construction and easily installs on a two-hour wood stud fire wall (e.g.. Type III construction) during framing. The new series features three models of top-flange hangers that connect floor trusses and joists to wood stud walls. The hangers feature enough space for two layers of 5/8 In. gypsum board (drywall) to be slipped into place after the framing is complete. They have been tested according to ASTM E814 and received F (flame) and T (temperature) ratings for use on one or both sides of the wall. These ratings verify that the DGF/DGHF/DGBF hangers do not reduce the two-hour fire wall assembly rating.
