Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered specifically for multifamily, multilevel Type III residential construction. Built to support 1-3/4 in. x 9-1/2 in. engineered wood members, this fire wall hanger is the first of its kind designed to install with a power nailer - allowing crews to complete framing connections faster before drywall goes up, keeping projects on schedule without compromising structural or fire code compliance. Tested to ASTM E814 and certified for use on both sides of the wall, the DGHT delivers a two-hour fire rating in the demanding assemblies where it matters most.
Key Features
- Power nailer compatible fastening - the first fire wall hanger designed for power-driven nail installation, reducing labor time during framing and helping keep construction timelines on track
- Loads tested and code listed for 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails - gives installers flexibility to use the nailing method that fits their workflow without losing code compliance
- Two-hour fire rating applies to 2x4 or thicker walls - meets fire assembly requirements for the wall thicknesses most common in multifamily and multilevel Type III residential framing
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies pairing hangers on opposite sides of a fire wall, reducing layout complexity and installation steps
- Space for two layers of 5/8 in. drywall after framing is complete - drywall can be slipped in after structural framing, allowing trades to sequence work more efficiently on the jobsite
- Two-hour Fire-Resistant rating certified under Intertek Design No. SST/WPCF 120-01 - provides third-party verified documentation for inspectors and code officials
- Made from 10-gauge steel with Zinc Galvanized G90 coating - heavy-gauge construction delivers structural strength while the corrosion-resistant finish supports long-term performance in varied jobsite conditions
Why This Product
- The only fire wall hanger built for power nailer installation - this design breakthrough means framing crews can fasten fire wall hangers as quickly as standard hangers, eliminating the slow, nail-by-nail process that typically delays fire-rated framing assemblies
- A single hanger that satisfies fire rating requirements on both sides of the wall - tested and rated for use on both faces of the assembly under ASTM E814, the DGHT simplifies specification and reduces the need to source separate products for each wall side
- Engineered for the realities of multifamily construction sequencing - the top-flange design and built-in drywall clearance let framers complete connections before wallboard installation, supporting the trade sequencing that keeps large residential projects moving
- Backed by independent third-party fire certification - the Intertek Design No. SST/WPCF 120-01 listing gives general contractors, inspectors, and architects documented proof of compliance, reducing approval friction on fire-rated assemblies

Frequently Asked Questions
What fire rating does the DGHT1.81/9.5 carry, and how was it tested?
The DGHT Top-Flange Fire Wall Hanger carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is certified under Intertek Design No. SST/WPCF 120-01. The rating applies to use on both sides of the wall with 2x4 or thicker wall assemblies.
Can this hanger be installed with a power nailer?
Yes. The DGHT is the first fire wall hanger specifically designed to install 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, providing flexibility on the jobsite.
How does the top-flange design accommodate drywall installation?
The top-flange design allows the hanger to be fully installed during framing, leaving space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This sequencing helps maintain construction schedules without compromising the fire wall assembly.
What is the minimum wall thickness required for back-to-back installation?
The DGHT's innovative top-flange design supports back-to-back installation on walls that are 2x6 or thicker (minimum). The two-hour fire rating applies to 2x4 or thicker walls, making the hanger versatile for a range of fire wall framing assemblies.
