Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger by Simpson is purpose-built for multifamily, multilevel Type III residential construction where certified fire wall separation is required. This patent-pending, load-tested hanger is the first fire wall hanger designed to install with a power nailer, cutting labor time before drywall goes up and helping keep construction timelines on track. Its innovative top-flange design lets two layers of 5/8-in. gypsum board slip into place after framing is complete, and it has been tested to ASTM E814 for fire-rated performance on both sides of the wall - making it a dependable solution for fire-rated joist hanger assemblies in demanding residential projects.
Key Features
- Power nailer compatible - tested for 1 1/2 in. and 2 1/2 in. nails - installs faster than traditional fire wall hangers, reducing labor hours before drywall stage and keeping projects on schedule
- Two-hour fire rating for 2x4 or thicker walls - meets fire separation requirements for multifamily and multilevel Type III construction with confidence
- Intertek certified under Design No. SST/WPCF 120-01, tested to ASTM E814 - provides a documented, code-listed rating recognized by inspectors and authorities having jurisdiction
- Top-flange design supports back-to-back installation on 2x6 (min.) walls - enables fire wall hanger placement on both sides of a shared wall without conflict, simplifying double-sided assemblies
- Accommodates two layers of 5/8-in. drywall after framing - the open top-flange profile lets gypsum board slide into position post-framing, preserving flexibility in the construction sequence
- Made from 10-gauge steel with G90 zinc galvanized coating - delivers the structural integrity and corrosion resistance required for long-term performance in engineered wood framing applications
- Fits engineered wood members sized 2 to 2-1/16 in. x 9-1/2 in. - designed for a precise fit with common engineered lumber dimensions used in contemporary residential framing
Why This Product
- A faster path to fire-rated framing compliance - as the first fire wall hanger engineered for power nailer installation, it eliminates the slow hand-nailing process that typically precedes drywall, helping crews recover time on tight project schedules
- Tested and listed on both sides of the wall - the ASTM E814 test standard confirms fire-rated performance for assemblies on either side of the fire wall, giving builders a single certified solution for the full assembly rather than two separate products
- Designed around the real construction sequence - the top-flange profile holds the joist in place while leaving the wall cavity open, so gypsum board layers can be added after framing is finished rather than requiring drywall to be installed mid-frame
- Made in the United States from 10-gauge galvanized steel - heavy-gauge domestic construction and a G90 zinc coating combine structural reliability with corrosion resistance for fire-rated joist hanger applications in multifamily residential buildings

Frequently Asked Questions
What fire rating does the DGHT2.1/9.5 carry, and how is it certified?
The DGHT2.1/9.5 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. This rating applies to 2x4 or thicker walls and covers fire-rated 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 or hand-installed nails, offering flexibility in installation method while saving time on the jobsite.
How does the top-flange design accommodate drywall installation?
The top-flange design allows framing to be completed first and provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is finished. This sequencing helps maintain project schedules in fire wall assemblies.
What are the nail schedule requirements for installing the DGHT2.1/9.5?
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.
