Product Details
Engineered and tested to perform, Simpson Strong-Tie® hangers are manufactured to the highest quality standards for structural strength and safety. The DU face-mount hanger is designed for lighter use to carry joist floor loads to a wood stud wall over two layers of 5/8" gypsum board (drywall). The DU hanger installs after the drywall is in place.
Key Features
- Testing verifies that the DU hangers do not reduce the two-hour fire wall assembly rating in either 2x4 or 2x6 walls.
- DU 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
- 14 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.

Load Tables
- 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.
- Hangers spaced closer than 16" o.c. shall reduce allowable load proportionately.
- Triangular nail holes may be filled with (4) additional 0.148" x 1 1/2" to achieve an allowable upliftl load of 750 lb.
- 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.
- 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.
- 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.
