Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered specifically for multifamily and multilevel Type III residential construction. Built to accept 2-5/16 in. x 14 in. engineered wood members, this top-flange hanger is the first fire wall hanger designed for power nailer installation, allowing crews to complete framing connections faster before drywall goes up. Tested to ASTM E814 and carrying a two-hour Fire-Resistant rating for use on both sides of the wall, the DGT delivers a code-listed fire wall connection solution backed by Simpson Strong-Tie expert service and technical support.
Key Features
- Power nailer compatible and code listed for 1-1/2 in. and 2-1/2 in. nails - allows faster, more consistent installation with a power nailer or by hand, reducing labor time before drywall begins.
- Two-hour Fire-Resistant rating (Intertek Design No. SST/WPCF 120-01) tested to ASTM E814 - provides verified fire protection on both sides of the wall, helping projects meet code requirements for fire wall assemblies with confidence.
- Innovative top-flange design for back-to-back installation on 2x6 (minimum) walls - simplifies hanger placement in fire wall assemblies where hangers must be paired on opposing sides, reducing coordination challenges in the field.
- Accommodates two layers of 5/8 in. drywall after framing is complete - the hanger stays out of the way during framing so drywall crews can slip gypsum board into place without removing or modifying the connector.
- Two-hour fire rating applies to 2x4 or thicker walls - covers a broad range of common wall assemblies, giving builders flexibility across different framing configurations.
- Made from 12-gauge steel with a G90 zinc galvanized finish - heavy-gauge construction delivers the structural strength fire wall applications demand, while the galvanized coating guards against corrosion over the life of the assembly.
Why This Product
- The first fire wall hanger built for power nailer installation - no other detail slows a framing crew more than reverting to hand nailing for specialty connectors. The DGT eliminates that bottleneck, letting crews maintain pace and keep construction schedules on track.
- A complete fire wall connection in one hanger - load tested, ASTM E814 fire tested, and rated for use on both sides of the wall, the DGT handles structural and fire-resistance requirements together rather than requiring separate engineering solutions for each.
- Designed around the full drywall workflow - because the top-flange profile reserves space for two layers of 5/8 in. gypsum board, framers and drywall crews can work in sequence without conflicts, reducing rework and job site coordination friction.
- Wide size range with a straightforward selection process - the DGT line is offered across multiple member sizes, making it easy to specify the correct hanger for the framing dimension at hand without custom fabrication or special engineering.

Frequently Asked Questions
What fire rating does the Simpson DGT2.37/14 carry, and how was it tested?
The DGT2.37/14 carries a two-hour Fire-Resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested in accordance with 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 Simpson DGT2.37/14 is specifically designed to be installed with a power nailer and is load tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails. It is also compatible with hand-installed nails of the same dimensions, providing flexibility on the job site.
How does the top-flange design accommodate drywall installation?
The innovative 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 work, helping maintain project schedules.
What is the minimum wall thickness required for back-to-back installation?
The DGT2.37/14 top-flange design supports back-to-back installation on walls that are at least 2x6 in dimension. The two-hour fire rating is applicable to walls that are 2x4 or thicker.
