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 two-hour fire-resistant wall assemblies are required. Designed to accept engineered wood members sized 2 1/2 in. x 24 in., this hanger is the first fire wall hanger built to install with a power nailer, cutting installation time before drywall goes up and helping keep framing schedules on track. Its innovative top-flange design accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, and its two-hour fire-resistant rating has been verified through testing to ASTM E814 for use on both sides of the wall.
Key Features
- Power nailer compatible - the first fire wall hanger designed for power-driven installation, so crews can fasten hangers faster before drywall goes up, reducing labor time on the framing phase.
- Tested and code listed for 1 1/2 in. and 2 1/2 in. nails, power-driven or hand-installed - gives installers flexibility to use the fastener method that best fits the job site without sacrificing code compliance.
- Two-hour fire-resistant rating on 2x4 or thicker walls (Intertek Design No. SST/WPCF 120-01) - meets the fire separation requirements common in multifamily and multilevel residential projects, supporting code compliance with confidence.
- Top-flange design for back-to-back installation on 2x6 (min.) walls - allows hangers to be mounted on opposing sides of the same wall, simplifying layout in double-loaded fire wall assemblies.
- Space built in for two layers of 5/8 in. drywall after framing - drywall slides into place post-framing without requiring hanger repositioning, keeping the work sequence efficient.
- 12-gauge steel with G90 zinc galvanized finish - heavy-gauge construction paired with corrosion-resistant coating means the hanger holds up in demanding construction environments through all phases of the build.
- Sized specifically for 2 1/2 in. x 24 in. engineered wood members - precise fit eliminates guesswork when selecting hardware for engineered lumber framing, reducing the risk of specification errors.
Why This Product
- A time-saving installation method that does not compromise fire performance - unlike conventional fire wall hangers that require hand nailing, this hanger is engineered for power nailer use, so crews move faster through the framing stage while still meeting a two-hour fire-resistant rating tested to ASTM E814.
- A fire rating verified on both sides of the wall - the two-hour rating applies to both faces of the assembly, making this hanger appropriate for the full fire wall system rather than only one side, which matters in multifamily construction where code compliance applies to the entire assembly.
- Engineered for the specific demands of Type III multifamily framing - the combination of top-flange geometry, back-to-back installation capability on 2x6 or thicker walls, and compatibility with 2 1/2 in. engineered wood members makes this hanger a purpose-built solution rather than a general-use connector adapted to a specialized application.
- Made in the United States and backed by Simpson technical support - domestic production and manufacturer-backed service provide contractors and specifiers with a reliable supply chain and access to expert guidance when questions arise on the job.

Frequently Asked Questions
What fire rating does the DGT2.56/24 carry, and how was it tested?
The DGT2.56/24 carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. The rating is certified under Intertek Design No. SST/WPCF 120-01.
Can this hanger be installed with a power nailer?
Yes. The DGT fire wall hanger is the first of its kind 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 installation flexibility on the jobsite.
What wall thickness is required for the two-hour fire rating to apply?
The two-hour fire rating applies to 2x4 or thicker walls. For back-to-back top-flange installation, a minimum 2x6 wall is required.
How does the top-flange design accommodate drywall installation?
The DGT's top-flange design provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after the framing is complete, allowing the hangers to be fully installed with a power nailer before drywall work begins.
