Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 3 1/2 in. x 14 in. engineered wood is a patent-pending, load-tested, and fire-rated joist hanger built for multifamily and multilevel Type III residential construction. Designed as the first fire wall hanger compatible with power nailer installation, it eliminates the need to hand-nail every connection, keeping framing crews on schedule before drywall goes up. The top-flange design allows two layers of 5/8 in. gypsum board to slip into place after framing is complete, and the hanger carries a two-hour fire-resistant rating tested to ASTM E814 for use on both sides of the fire wall.
Key Features
- Compatible with power-driven or hand-installed nails - load tested and code listed for both 1 1/2 in. and 2 1/2 in. nails, giving installers the flexibility to use a power nailer or nail by hand without sacrificing code compliance.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - tested to ASTM E814 and rated for use on both sides of the wall, satisfying fire wall requirements for covered project types when applied to 2x4 or thicker walls.
- Innovative top-flange design - enables back-to-back installation on 2x6 (minimum) walls, simplifying layout and reducing hardware complexity at fire wall connections.
- Integrated drywall clearance - provides space for two layers of 5/8 in. gypsum board to be slipped in after framing, so finish work can proceed without cutting around or removing the hanger.
- 12-gauge steel construction with G90 zinc galvanized finish - delivers the structural strength and corrosion resistance required for demanding residential framing environments.
- Wide range of available sizes - the DGT series is offered in multiple sizes, making it straightforward to select the right hanger for the specific engineered lumber dimensions on a given project.
Why This Product
- The first fire wall hanger built for power nailer use - this design breakthrough lets crews install hangers before drywall with a power nailer rather than by hand, directly reducing labor time and helping keep multifamily construction projects on schedule.
- Fire rating on both sides of the wall in one hanger - because the two-hour rating applies to both faces of the fire wall, there is no need to source separate rated hardware for each side, simplifying procurement and inspection documentation.
- Engineered for the full fire wall assembly workflow - the top-flange configuration accommodates double-layer drywall installation after framing is complete, so structural connections and fire-resistive assemblies work together without requiring rework or field modifications.
- Backed by tested, listed performance data - with ASTM E814 fire testing and Intertek certification, the hanger arrives with documented code support, reducing the burden on project teams to justify hanger selection during plan review or inspection.
