Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested hanger engineered for 7 in. x 18 in. engineered wood joists in multifamily and multilevel Type III residential construction. Carrying a two-hour fire-resistant rating tested to ASTM E814 and rated for use on both sides of the wall, this top-flange hanger is the first fire wall hanger designed to install with a power nailer - keeping framing crews moving and construction schedules on track. Its innovative design leaves room for two layers of 5/8 in. gypsum board to be slipped into place after framing is complete, streamlining the transition from structure to drywall on fire wall assemblies.
Key Features
- Power nailer compatible, code listed for 1 1/2 in. and 2 1/2 in. nails - lets crews install with a power nailer or by hand, cutting labor time before drywall and keeping projects on schedule
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - meets fire wall assembly requirements for multifamily and multilevel Type III residential builds, rated for use on both sides of the wall
- Top-flange design for back-to-back installation on 2x6 (min.) walls - allows hangers to be positioned on opposing sides of the wall for clean, structurally sound fire wall assemblies without conflict
- Accommodates two layers of 5/8 in. drywall after framing - gypsum board slips into place post-framing so crews are not interrupted during structural work
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility gives builders flexibility across common framing configurations
- Made from 10-gauge steel with G90 zinc galvanized finish - heavy-gauge construction delivers the load capacity fire wall applications demand, while the galvanized coating provides corrosion resistance for long-term performance
Why This Product
- A fire wall hanger built for power-tool installation - as the first fire wall hanger designed specifically for use with a power nailer, the Simpson DGHT cuts installation time before drywall goes up, a meaningful advantage on large multifamily and multilevel projects where schedule pressure is constant
- Tested and certified for two-hour fire wall assemblies - load testing to ASTM E814 and certification under Intertek Design No. SST/WPCF 120-01 give builders and inspectors the documented third-party verification needed for code-compliant fire wall construction
- Designed around the full assembly sequence - the top-flange configuration and built-in clearance for two layers of 5/8 in. gypsum board mean the hanger works with the construction workflow rather than against it, reducing rework and coordination issues between framing and drywall trades
- Sized and rated for heavy engineered wood framing - the 7 in. x 18 in. member size and 10-gauge steel construction address the structural demands of deep-joist, multilevel residential fire wall assemblies where undersized hardware is not an option

The DGHT7.12/18 carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is rated for use on both sides of the wall. The rating is certified under Intertek Design No. SST/WPCF 120-01 and applies to 2x4 or thicker walls.
Can this hanger be installed using a power nailer?
Yes. The DGHT is the first fire wall hanger designed specifically for installation with a power nailer. It is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails, as well as hand-installed nails of the same sizes.
Does the DGHT7.12/18 accommodate drywall installation after framing is complete?
Yes. The top-flange design provides space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete, streamlining the construction sequence and helping keep projects on schedule.
What are the minimum wall requirements for back-to-back installation of this hanger?
The DGHT7.12/18's innovative top-flange design supports back-to-back installation on walls that are a minimum of 2x6 in size. The two-hour fire rating applies to 2x4 or thicker walls.
