The Simpson Strong-Tie DGBF fire wall hangers are a great time saving solution for multi-level building construction. These hangers are easily installed on either 2×4 or 2×6 two-hour wood stud fire walls while framing. These hangers 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 hangers do not reduce the two-hour fire wall assembly rating. The DGBF is a top-flange hanger specifically designed to connect wood beams to wood stud walls. The hanger features an angled joist stop that prevents the beam from seating too far back in the stirrup, creating space for the drywall to be installed between the beam and the wall after framing. The DGBF hanger provides support for loads up to 3,015 lb. when installed over a double stud in Type III construction.

Installation:

• Use all specified fasteners.
• Hangers are mounted like a standard top-flange hanger.
• A double stud is required below the hanger.
• When welded to a steel header, the hanger requires two 2″ fillet welds along the sides of the top flange and (8) 0.148″ x 1 1/2″ joist nails to achieve a download of 3,000 lb.; the weld size needs to match the hangers thickness.
• Table uplift loads apply to welded applications.
• Apply two 1/4″-diameter beads of fire-resistant mortar caulk directly to top-of-wall plates for the first 6″ on either side of top flange. See Intertek design listing for detail.
• Stud wallplate splices must occur at a stud location.
