Engineered and tested to perform, Simpson Strong-Tie® hangers are manufactured to the highest quality standards for structural strength and safety. The DHU face-mount hanger is designed to carry joist floor loads to a wood stud wall over two layers of 5/8" gypsum board (drywall). The DHU hanger installs after the drywall is in place.

Key Features

  • DHU hangers in widths of 2 1/2" or greater may be ordered with one flange concealed.
  • Available for order skewed up to 45°.
  • Testing verifies that the DHU hangers do not reduce the two-hour fire wall assembly rating in either 2x4 or 2x6 walls.
  • DHU fire wall hangers are code listed for structural use under ICC-ES ESR-2552.
  • 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 in Intertek Design No. SST/WPCF 120-01. If hangers are installed on both sides of the wall, then it must be a 2x6 wall.

Material

  • 12 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners; see General Notes.
  • Strong-Drive® SDS Heavy-Duty Connector screws are provided with the hanger.
  • Drywall is installed first.
  • Mounted with top of hanger flush with top of wall and tight to the drywall.
  • Wall top plates must be restrained to prevent rotation. Where gravity load on top of wall is less than 150 plf, use a stud-plate tie connector at the back of each stud or provide equivalent restraint by another method as determined by designer.
  • Upper plate splices must occur at a stud location.

Options

  • May be ordered with one flange concealed for widths at least 2 1/2" wide; specify which flange when ordering. Use 74% of the table downloads and 100% of table uplift loads.
  • May be ordered skewed up to 45°. Use 75% of the table downloads and 50% of table uplift loads.

Patent Information

  • US Patent 9,394,680

Load Tables

DHU Load Table
  1. Loads assume 5/8" Type X drywall attached per IBC. Wall assembly must consist at a minimum of two 2x4 plate members with studs spaced not more than 16" o.c. For alternative solutions to mounting over a single layer of drywall, refer to the technical bulletin T-C-TFWALL.
  2. Hangers spaced closer than 16" o.c. shall reduce allowable load proportionately.
  3. Triangular nail holes may be filled with (4) additional 0.148" x 1 1/2" to achieve an allowable upliftl load of 750 lb.
  4. DF carried members with a minimum of 1 1/2" x 2 1/2" solid sawn chord dimensions may increase Allowable Uplift Load to 170 lb.
  5. Allowable downloads may be increased to 1,885 lb. for DF/SP and 1,585 lb. for SPF/HF using the DHU3.56 /24 model.
  6. For a DHU two-sided (back-to-back) application on a 2x6 wall, use 1,200 lb. allowable download for DF/SP plates and use 1,005 lb. for SPF/HF plates.
  7. For installations of two layers of gypsum wall board over 5/8" maximum wood structural panel, the DHU has an allowable download of 1,975 lb. for DF/SP plates and 1,660 lb. for SPF/HF plates.
