Engineered Wood & Structural Composite Lumber Connectors
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. MATERIAL: DU—14 gauge; DHU and DHUTF—12 gauge FINISH: Galvanized INSTALLATION: • Use all specified fasteners. See General Notes. • Simpson Strong-Tie® 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. Use an SSP 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. CODES: See page 12 for Code Reference Key Chart.

1. Loads assume 5⁄8" Type X drywall attached per IBC. Wall assembly must consist of minimum two 2x4 plate members with studs spaced not more than 16" o.c. For alternate solutions to mounting over single layer of drywall, refer to the technical bulletin T-C-TFWALL13 at www.strongtie.com. 2. Hangers spaced closer than 16" o.c. shall reduce capacity proportionately. 3. Triangle nail holes may be filled with (4) additional 10dx1 1⁄2" to achieve an Allowable Uplift Load of 750 lbs. 4. DF carried members with minimum 1 1⁄2" x 2 1⁄2" solid sawn chord dimension may increase Allowable Uplift Load to 170 lbs. 5. Allowable downloads may be increased to 1885 lbs. for DF/SP and 1585 lbs. for SPF/HF using the DHU3.56/24 or DHUTF3.56/24 models.
