Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered for multifamily, multilevel Type III residential construction requiring certified fire-rated framing assemblies. Built to support 3-1/2 in. x 20 in. engineered wood members, this top-flange hanger carries a two-hour fire rating tested in accordance with ASTM E814 and is fire rated for use on both sides of the wall - making it a reliable solution for fire wall assemblies in demanding structural applications. Its innovative design accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, and it is the first fire wall hanger of its kind designed for installation with a power nailer, helping crews stay on schedule before drywall begins.
Key Features
- Power nailer compatible, first of its kind - installs with a power nailer or by hand using 1-1/2 in. or 2-1/2 in. nails, dramatically reducing labor time during fire wall framing before drywall is hung
- Two-hour fire rating on both sides of the wall - tested to ASTM E814 and rated for dual-side fire wall assemblies, giving contractors the code confidence needed for multifamily and Type III residential projects
- Intertek certified fire-resistant assembly - listed under Intertek Design No. SST/WPCF 120-01, providing a documented, third-party verified rating that supports code submittals and inspections
- Top-flange design for back-to-back installation - engineered for back-to-back hanger placement on 2x6 (minimum) walls, simplifying layout and reducing the need for additional blocking or hardware in paired assemblies
- Post-framing drywall clearance built in - the seat geometry provides space for two layers of 5/8 in. drywall to be inserted after structural framing is complete, keeping the construction sequence efficient and uninterrupted
- 10-gauge steel with G90 zinc galvanized finish - heavy-gauge construction delivers load capacity for large engineered wood members while the galvanized coating provides corrosion resistance in exposed or semi-exposed framing environments
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall thickness compatibility means the hanger works across a wide range of common residential framing configurations without special conditions
Why This Product
- Engineered to accelerate fire wall framing - as the first fire wall hanger designed for power nailer installation, it removes a traditional bottleneck in the pre-drywall phase, helping construction teams maintain project schedules on multilevel residential builds
- One hanger, two certified fire ratings - the DGHT carries both an ASTM E814 test rating and the Intertek Design No. SST/WPCF 120-01 fire-resistant rating, giving contractors dual-documentation support for code compliance on both sides of a fire wall
- Designed for the full construction sequence - the top-flange configuration allows drywall to be installed after framing is complete rather than requiring coordination between trades mid-frame, reducing rework and scheduling conflicts on multifamily job sites
- American-made with heavy-gauge, corrosion-resistant construction - 10-gauge steel and a G90 galvanized finish deliver structural integrity and long-term durability, making this hanger a dependable choice for fire-rated assemblies where performance and longevity matter

Frequently Asked Questions
What fire rating does the DGHT3.62/20 carry, and how was it tested?
The DGHT3.62/20 carries a two-hour fire rating. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. It also holds the two-hour Fire-Resistant rating under Intertek Design No. SST/WPCF 120-01.
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 this hanger be installed with a power nailer?
Yes. The DGHT is the first fire wall hanger 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 or hand-installed nails, offering flexibility in installation method.
How does the top-flange design accommodate drywall installation?
The top-flange design provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after the framing is complete, allowing drywall installation to proceed without interference from the hanger.
