Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested connector engineered for multifamily, multilevel Type III residential construction where fire wall separation is required. Designed to accept 5-1/4 in. x 11-7/8 in. engineered wood framing members, this hanger carries a two-hour fire-resistant rating tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, making it code-listed for use on both sides of the wall. Its innovative top-flange configuration allows two layers of 5/8-in. gypsum board to be slipped into place after framing is complete, and it is the first fire wall hanger built to work with a power nailer - helping crews move faster and keep projects on schedule.
Key Features
- Power nailer compatible installation - the first fire wall hanger designed for power-driven nails, reducing installation time before drywall and helping keep construction timelines on track
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - meets code requirements for fire wall applications on both sides of the wall, giving builders confidence in compliance
- Tested and code listed for 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails - provides verified fastening flexibility so crews can use the nail length best suited to their workflow
- Top-flange design for back-to-back installation on 2x6 (minimum) walls - allows paired hangers to be set before drywall goes up, streamlining the framing sequence on fire wall assemblies
- Built-in space for two layers of 5/8-in. drywall - drywall slides in after framing is complete, so hanger placement never has to wait on the finishing schedule
- Fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility supports a wide range of multifamily and multilevel framing layouts
- Made from 10-gauge steel with G90 zinc galvanized coating - heavy-gauge construction delivers the load capacity and corrosion resistance demanded by structural fire wall connections
Why This Product
- A purpose-built solution for fire wall framing - unlike standard joist hangers, the DGHT was specifically designed and load-tested for fire wall applications in multifamily and multilevel Type III residential construction, with a certified two-hour fire-resistant rating on both sides of the wall
- Speeds up the job site without sacrificing compliance - as the first fire wall hanger engineered for power nailer installation, it cuts labor time during framing while remaining fully code-listed, helping crews stay on schedule before drywall installation begins
- Simplifies sequencing with a post-frame drywall installation - the top-flange design lets two layers of 5/8-in. gypsum board be added after framing is complete, eliminating the need to coordinate hanger placement around the drywall trade
- Built for long-term structural performance - 10-gauge steel construction paired with a G90 zinc galvanized finish delivers the strength and corrosion resistance needed for demanding fire-rated structural connections in residential construction

Frequently Asked Questions
What is the fire rating of the Simpson DGHT5.37/11.88, and how was it certified?
The DGHT5.37/11.88 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 fire rating is certified under Intertek Design No. SST/WPCF 120-01, and it applies to 2x4 or thicker walls.
Can this hanger be installed with a power nailer?
Yes. The DGHT is the first fire wall hanger specifically designed to be installed 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, offering flexibility on the job site and saving time before drywall installation.
How does the top-flange design accommodate drywall installation?
The top-flange design of the DGHT provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This allows drywall to be installed without interference from the hanger, streamlining the construction sequence on fire wall assemblies.
What are the nail requirements for installing the DGHT5.37/11.88?
Install with (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. Both power-driven and hand-installed nail options are code listed.
