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 where fire-rated wall assemblies are required. Built to support 3-1/2 in. x 22 in. engineered wood joists, this top-flange hanger carries a two-hour fire rating tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01 - making it a code-compliant solution for fire wall assemblies on both sides of the wall. Its innovative design is the first of its kind to support power nailer installation, allowing crews to complete framing connections faster and keep construction schedules on track before drywall goes up.
Key Features
- Power nailer compatible - first fire wall hanger of its kind to support this method - eliminates hand-nailing delays during framing, keeping your project on schedule before drywall installation begins.
- 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 fastener length that suits the application without sacrificing code compliance.
- Two-hour fire rating applies to 2x4 or thicker walls - meets fire-rated assembly requirements on both sides of the wall, supporting safe multifamily and multilevel residential construction.
- Top-flange design allows back-to-back installation on 2x6 (min.) walls - simplifies fire wall framing at shared wall conditions without requiring specialized blocking or additional hardware.
- Accommodates two layers of 5/8 in. drywall after framing is complete - drywall can be slipped into place post-framing, reducing interference between trades and maintaining workflow efficiency.
- Made from 10-gauge steel with a G90 zinc galvanized finish - heavy-gauge construction delivers the structural strength needed for large-format engineered wood joists, while the corrosion-resistant coating supports long-term durability.
- Tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01 - independently verified fire-resistance rating gives architects, inspectors, and contractors a clear path to code approval.
Why This Product
- A fire wall hanger built around how crews actually work - as the first fire wall hanger designed for power nailer installation, the Simpson DGHT cuts framing labor time without compromising the load-tested, code-listed performance required for fire-rated assemblies.
- Verified two-hour fire resistance on both sides of the wall - tested to ASTM E814 and certified by Intertek, this hanger meets the fire-rated wall assembly demands of multifamily and multilevel Type III residential projects with independently documented proof.
- Designed to keep trades moving - the top-flange configuration allows two layers of 5/8 in. drywall to be installed after framing is complete, so drywall crews are not dependent on hanger installation sequencing and overall project timelines stay intact.
- Back-to-back capability on a single wall - the innovative top-flange design supports back-to-back joist hanger installation on 2x6 (min.) walls, making it a practical choice for shared fire wall conditions common in multifamily construction.

Frequently Asked Questions
What fire rating does the DGHT3.62/22 carry, and how was it tested?
The DGHT3.62/22 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 two-hour fire rating applies to 2x4 or thicker walls and is valid for use on both sides of the wall.
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 nails, as well as hand-installed nails, providing installation flexibility on the job site.
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 keep construction on schedule without requiring drywall to be in place before hanging joists.
What are the fastener requirements for proper installation of the DGHT3.62/22?
Proper installation requires: (6) 0.148 in. x 1-1/2 in. OR 0.148 in. x 2-1/2 in. nails in the top; (2) 0.148 in. x 1-1/2 in. nails OR (4) 0.148 in. x 2-1/2 in. nails in the face; and (6) 0.148 in. x 1-1/2 in. nails in the joist. Using the specified nail schedule is essential to maintain the load ratings and fire rating certification.
