Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested connector engineered for multifamily and multilevel Type III residential construction, where fire-rated framing assemblies are required. Designed to support 1-3/4 in. x 9-1/2 in. engineered wood members at fire wall locations, this top-flange hanger carries a two-hour fire-resistant rating tested to ASTM E814 and is approved for use on both sides of the wall. 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 built to install with a power nailer - helping crews stay on schedule without sacrificing code compliance.
Key Features
- Power nailer compatible - the first fire wall hanger designed for power-driven installation, reducing labor time before drywall goes up and keeping projects on schedule
- 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 standard fastening methods without sacrificing load performance
- Two-hour fire rating applies to 2x4 or thicker walls - meets fire-resistance requirements for common wall assemblies in multifamily and multilevel residential construction
- Intertek Design No. SST/WPCF 120-01, tested to ASTM E814 - provides third-party verified, code-recognized fire performance documentation for inspections and submittals
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hanger placement at shared fire walls without requiring special framing modifications
- Space for two layers of 5/8 in. drywall after framing - lets crews complete framing first and finish the fire-rated drywall assembly afterward, improving workflow sequencing
- Made from 12-gauge steel with a Zinc Galvanized G90 finish - delivers structural rigidity and corrosion resistance suited for protected interior framing environments
Why This Product
- Designed specifically for fire wall framing - unlike standard joist hangers, the DGT is load tested and carries a two-hour fire-resistant rating for use on both sides of the wall, making it a purpose-built solution for code-compliant fire wall assemblies in multifamily residential projects
- First fire wall hanger compatible with power nailer installation - this design advantage directly reduces installation time before drywall, helping contractors maintain project timelines on multistory builds where fire wall framing is a critical path task
- Supports a clean construction sequence - the top-flange configuration holds the joist securely while leaving room for two layers of 5/8 in. gypsum board to be installed after framing, so structural and fire-rated finish work can proceed in the most efficient order
- Backed by Simpson engineering and made in the United States - the DGT comes with expert technical support and is widely available, giving builders confidence in both product performance and project continuity

Frequently Asked Questions
What fire rating does the DGT1.81/9.5 carry, and how was it tested?
The DGT1.81/9.5 carries a two-hour fire-resistant rating, tested according to ASTM E814. It is fire rated for use on both sides of the wall and holds Intertek Design No. SST/WPCF 120-01. The two-hour fire rating applies to 2x4 or thicker wall assemblies.
Can this hanger be installed with a power nailer?
Yes. The DGT fire wall hanger 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, providing flexibility on the job site while saving time before drywall installation.
What joist member size does the DGT1.81/9.5 support, and what are its key dimensions?
This hanger is designed for 1-3/4 in. x 9-1/2 in. engineered wood members. It features a seat width of 1-13/16 in. and is made from 12-gauge steel with a G90 zinc galvanized finish for corrosion resistance.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design allows the hanger to be installed back-to-back on 2x6 (minimum) walls and provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete - keeping the construction sequence efficient and on schedule.
