This product's information may differ depending on the category of use. You are currently viewing details related to Fire Wall Hangers for Plated Truss.

The DU/DHU face-mount and the DHUTF top-mount hangers are designed to carry joist floor loads to a wood stud wall through two layers of 5/8" gypsum board (drywall). These hangers install after the drywall is in place. The hangers come in sizes that accommodate most joists used in multi-family construction including I-joists and trusses.

All three fire wall hangers are code listed under ICC-ES ESR-2552.

All three fire wall hangers are fire-resistant F (flame) and T (temperature) rated in Intertek Design No. SST/WPCF 120-01

Material

  • DU — 14 gauge; DHU and DHUTF — 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.
  • DU and DHU are 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

  • The DHU 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.
  • The DHU/DHUTF may be ordered skewed up to 45°. Use 75% of the table downloads and 50% of table uplift loads.

Two-Hour, Fire-Rated Wall

  • Simpson Strong-Tie has completed ASTM E814 standard testing at an accredited laboratory. The use of the DU/DHU/DHUTF hangers does not reduce the two-hour, fire wall assembly rating. The hangers tested provide an F (flame) and T (temperature) rating.

  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 or DHUTF 3.56 /24 models.
  6. For a DHU/DHUTF 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 a DU two-sided (back-to-back) application on a 2x6 wall, use 1,075 lb. allowable download for DF/SP plates and 880 lb. for SPF/HF plates.
  8. For installations of two layers of gypsum wall board over 5/8" maximum wood structural panel, the DHU/DHUTF has an allowable download of 1,975 lb. for DF/SP plates and 1,660 lb. for SPF/HF plates.
  9. For the DU, if a 5/8" structural wood panel is used between the drywall and the studs, use 1,110 lb. allowable download for DF/SP plates and 880 lb. for SPF/HF plates.
