Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2-5/16 in. x 20 in. engineered wood is a patent-pending, load-tested, and fire-rated joist hanger built for multifamily and multilevel Type III residential construction. Its innovative top-flange design makes it the first fire wall hanger engineered to install with a power nailer, cutting time from the framing phase and helping keep construction schedules on track before drywall goes up. Carrying a two-hour fire-resistant rating tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, this hanger is fire rated for use on both sides of the wall, making it a reliable choice for fire wall assemblies in demanding residential projects.
Key Features
- Power nailer and hand-nail compatible, code listed for 1-1/2 in. and 2-1/2 in. nails - gives crews the flexibility to work with their preferred installation method without sacrificing code compliance or load performance.
- Two-hour fire-resistant rating on 2x4 or thicker walls - meets fire wall assembly requirements on both sides of the wall, supporting code compliance in multifamily and multilevel residential builds.
- Top-flange design for back-to-back installation on 2x6 minimum walls - allows pairs of hangers to be set simultaneously, reducing steps during framing and improving installation efficiency.
- Accommodates two layers of 5/8 in. gypsum board after framing is complete - drywall slides into place post-framing without rework, keeping the construction sequence clean and the project on schedule.
- Made from 12-gauge steel with a G90 zinc galvanized finish - delivers the structural strength and corrosion resistance needed for long-term performance in fire wall framing applications.
- Sized for 2-5/16 in. x 20 in. engineered wood members - precisely matched to common engineered lumber dimensions used in multilevel framing, eliminating guesswork when specifying the correct hanger.
Why This Product
- The first fire wall hanger designed for power nailer installation - this patent-pending design eliminates the hand-nailing bottleneck that slows fire wall framing, helping crews move faster before drywall installation begins.
- Independently tested and fire rated for both sides of the wall - with ASTM E814 testing and Intertek certification, this hanger gives builders and inspectors documented proof of compliance for two-hour fire wall assemblies.
- Engineered specifically for multifamily and multilevel Type III residential construction - the combination of fire rating, top-flange geometry, and compatibility with engineered lumber makes this hanger purpose-built for the project types where fire wall requirements are most critical.
- Simplifies the framing-to-drywall transition - because the top-flange design creates space for two layers of 5/8 in. drywall to be added after framing, contractors avoid costly sequence conflicts and keep trades moving without interruption.

Frequently Asked Questions
What fire rating does the DGT2.37/20 carry, and how was it tested?
The Simpson DGT2.37/20 carries a two-hour fire-resistant rating, tested in accordance with 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 walls.
Can this hanger be installed with a power nailer?
Yes. The DGT is the first fire wall hanger specifically 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 nails, as well as hand-installed nails, providing 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 framing without obstructing subsequent drywall application, keeping the construction schedule on track.
What steel gauge and coating does this hanger use?
The DGT2.37/20 is manufactured from 12-gauge steel and features a Zinc Galvanized (G90) coating for corrosion resistance, ensuring durability in demanding residential construction environments.
