Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger by Simpson is a patent-pending, load-tested connector engineered for multifamily, multilevel Type III residential construction where fire-rated wall assemblies are required. Carrying a two-hour fire-resistant rating tested to ASTM E814, this hanger is the first fire wall hanger designed to install with a power nailer, saving critical time before drywall is hung and helping keep projects on schedule. Its innovative top-flange design accommodates two layers of 5/8-in. gypsum board slipped into place after framing is complete, and it has been tested and rated for fire-rated performance on both sides of the wall.
Key Features
- Power nailer compatible, load tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - allows faster installation before drywall goes up, keeping construction timelines on track without sacrificing code compliance.
- Two-hour fire-resistant rating applies to 2x4 or thicker walls - meets fire-rated wall assembly requirements for multifamily and multilevel residential projects, backed by Intertek Design No. SST/WPCF 120-01.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - enables clean, symmetrical fire wall hanger placement on both sides of the wall without interference between connectors.
- Space for two layers of 5/8-in. drywall after framing is complete - drywall can be slipped into place post-framing, streamlining the sequencing of trades on the job site.
- Tested to ASTM E814 and fire rated for use on both sides of the wall - provides verified, code-recognized performance on full fire wall assemblies, not just one face.
- Made from 10-gauge steel with a Zinc Galvanized G90 finish - heavy-gauge construction delivers structural strength while the G90 galvanized coating provides corrosion resistance for long-term durability.
Why This Product
- The first fire wall hanger built for power nailer installation - no other fire wall hanger offers this capability, which directly reduces labor time during framing and helps avoid costly schedule delays before drywall crews arrive.
- A true two-hour fire rating verified by independent testing - tested to ASTM E814 under Intertek Design No. SST/WPCF 120-01 and rated for both sides of the wall, giving builders, engineers, and inspectors confidence that the assembly meets code without guesswork.
- Engineered specifically for fire wall framing in multifamily construction - the top-flange geometry and back-to-back installation capability on 2x6 minimum walls make this hanger a purpose-built solution for Type III residential fire wall assemblies, not a general-purpose hanger adapted for the application.
- Post-framing drywall installation built into the design - the hanger's geometry reserves space for two layers of 5/8-in. gypsum board, allowing crews to sequence framing and drywall independently and avoid rework at the wall assembly.

Frequently Asked Questions
What fire rating does the DGHT1.81/11.88 carry, and how was it tested?
The DGHT1.81/11.88 carries a two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall.
What wall thickness is required for the two-hour fire rating to apply?
The two-hour fire rating applies to 2x4 or thicker walls. For back-to-back installation using the top-flange design, a minimum 2x6 wall is required.
Can the DGHT1.81/11.88 be installed with a power nailer?
Yes. It is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails (0.148 in. diameter), making it the first fire wall hanger designed for power nailer installation. Hand-installed nails of the same specifications are also approved.
How does the top-flange design accommodate drywall installation?
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, allowing the hanger to be fully nailed off before drywall work begins and keeping the construction sequence efficient.
