Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2 1/2 in. x 16 in. Engineered Wood from Simpson is a patent-pending, load-tested connector engineered for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Carrying a two-hour Fire-Resistant rating tested to ASTM E814, this hanger is fire rated for use on both sides of the wall and is the first fire wall hanger designed to install with a power nailer - so framing crews can work faster before drywall goes up and keep construction timelines on track. The innovative top-flange design provides clearance for two layers of 5/8 in. gypsum board to be slipped into place after framing is complete, and the hanger is code listed for both power-driven and hand-installed nails.
Key Features
- Power nailer compatible and code listed - load tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails, reducing installation time compared to connectors that require hand nailing only
- Two-hour Fire-Resistant rating (Intertek Design No. SST/WPCF 120-01) - tested to ASTM E814 for fire-rated use on both sides of the wall, giving builders and inspectors confidence in code compliance for fire wall assemblies
- Top-flange design for back-to-back installation - engineered for back-to-back installation on 2x6 (minimum) walls, allowing paired hangers to share the same header without conflict
- Post-framing drywall clearance - accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, so crews are not forced to interrupt their workflow to hang drywall mid-frame
- Two-hour fire rating on 2x4 or thicker walls - the fire rating applies to 2x4 or thicker wall assemblies, covering the most common framing scenarios in multifamily residential construction
- 12-gauge steel with G90 galvanized coating - heavy-gauge construction delivers structural rigidity while the zinc galvanized finish provides corrosion resistance for long-term performance
- Sized for 2 1/2 in. x 16 in. engineered wood members - precise fit for the specified joist size means no field modification is needed, protecting the integrity of the fire-rated assembly
Why This Product
- The first fire wall hanger built for power nailer installation - this patent-pending design eliminates the hand-nailing bottleneck that slows framing on fire wall assemblies, helping multifamily projects stay on schedule without sacrificing the code-listed load performance builders require
- A single hanger that satisfies both structural and fire-rating requirements - load tested and carrying a two-hour Fire-Resistant rating under Intertek Design No. SST/WPCF 120-01 (tested to ASTM E814), the DGT replaces the need to source separate structural and fire-rated solutions for Type III residential fire walls
- Designed around the real sequence of the job site - the top-flange configuration lets framing crews complete the structure first and then slide two layers of 5/8 in. drywall into position afterward, reducing rework and coordination delays between framing and drywall trades
- Backed by rigorous third-party testing and wide size availability - the DGT line is offered in a wide range of sizes and is supported by expert technical service, making it straightforward to specify and confirm the right connector for each application in a fire-rated wall assembly

Frequently Asked Questions
What fire rating does the DGT2.56/16 carry, and how was it tested?
The DGT2.56/16 carries a two-hour Fire-Resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. The two-hour fire rating applies to 2x4 or thicker walls.
Can this hanger be installed with a power nailer?
Yes. The DGT is the first fire wall hanger designed specifically for installation with a power nailer. It is load tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails, as well as hand-installed nails, giving installers flexibility on the job site.
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 framing is complete. This allows the hanger to be fully installed during the framing stage without interfering with subsequent drywall application.
What nail schedule is required to install the DGT2.56/16?
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.
