The patent-pending DGF fire wall hanger series features three models and is an ideal time-saving solution for multi-family, multi-level building construction. The hangers easily install on a two-hour wood stud fire wall (e.g., Type III construction) during framing. They feature enough space for two layers of 5/8" gypsum board (drywall) to be slipped into place after the framing is complete. 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 DGF is a top-flange hanger that connects floor trusses and joists to wood stud walls. The hanger features a v-shaped joist stop at the top whose unique design prevents the joist from seating too far back in the stirrup, creating space for the drywall to be installed between the joist and the wall after framing. This economical hanger provides joist support for the majority of Type III construction projects.

Key Features

  • The two-hour fire wall assembly rating applies to either 2x4 or 2x6 walls
  • If hangers are installed back to back on both sides of the wall, the wall must be 2x6
  • The DGF has been tested according to ASTM E814 and received F (flame) and T (temperature) ratings that can be found in Intertek Design No. SST/WPCF 120-01

Material

  • 12 gauge

Finish

  • Zinc galvanized, G90

Installation

  • Use all specified fasteners.
  • Hangers are mounted like a standard top-flange hanger.
  • I-joists require web stiffeners to achieve full table loads. I-joists without web stiffeners have reduced loads as shown in the table.
  • When welded to a steel header, the hanger requires four 2" fillet welds along the sides of the top flanges and (6) joist nails to achieve a download of 1,650 lb.; the weld size needs to match the hanger’s thickness.
  • Table uplift loads apply to welded applications.
  • Stud wall–plate splices must occur at a stud location.

  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Allowable loads are for 2x4 minimum stud wall or nailer. Back-to-back installations require a minimum 2x6. Wall design by Designer.
  3. Hangers spaced closer than 16" o.c. shall reduce allowable load proportionately.
  4. DGBF installation requires a minimum (2) 2x4 stud or post in the wall at hanger location. Post design by Designer.
  5. DGHF hangers may be skewed up to 45. Skew and offset options cannot be combined.
  6. Face nails for DGHF (offset) may be installed in any two holes.
  7. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
