Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested hanger engineered specifically for multifamily, multilevel Type III residential construction requiring fire-rated framing assemblies. Sized for 2 1/2 in. x 20 in. engineered wood members, it carries a two-hour fire-resistant rating tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01 for use on both sides of the wall. Its innovative top-flange design makes it the first fire wall hanger built to install with a power nailer, reducing labor time before drywall and helping keep construction schedules on track.
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 and avoid costly schedule delays.
- Loads tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - gives contractors verified, code-compliant fastener flexibility whether using a nailer or swinging a hammer.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) tested to ASTM E814 - meets fire wall assembly requirements on both sides of the wall, supporting compliance in Type III residential projects.
- Two-hour fire rating applies to 2x4 or thicker wall assemblies - broad wall-thickness compatibility makes this hanger practical across a wide range of structural framing configurations.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hangers to share a common bearing surface, simplifying layout and reducing material at fire wall locations.
- Accommodates two layers of 5/8 in. drywall after framing is complete - the space built into the hanger lets gypsum board slip into place post-framing, so drywall crews are never held up waiting on hangers.
- Made from 10-gauge steel with G90 zinc galvanized finish - heavy-gauge construction delivers the structural strength fire wall applications demand, while the galvanized coating resists corrosion in exposed framing environments.
Why This Product
- Schedule-saving installation - because the DGHT was purpose-built for power nailer use, framing crews can install fire wall hangers at full nailer speed rather than hand-nailing, protecting project timelines on multifamily and multilevel jobs.
- A verified two-hour fire rating on both sides of the wall - with testing to ASTM E814 and third-party certification from Intertek, this hanger gives builders and inspectors a documented, code-referenced fire-resistant assembly rather than an assumed one.
- Post-framing drywall flexibility - the hanger's built-in clearance for two layers of 5/8 in. gypsum board means fire wall drywall can be installed after the structure is complete, reducing the coordination burden between framing and finishing trades.
- Designed for the demands of Type III multifamily construction - load-tested performance, back-to-back top-flange geometry, and a two-hour fire-resistant rating combine in a single connector that addresses the specific structural and life-safety requirements of multilevel residential fire walls.

Frequently Asked Questions
What fire rating does the Simpson DGHT2.56/20 carry?
The DGHT2.56/20 carries a two-hour fire-resistant rating. It has been tested in accordance with 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 and applies to 2x4 or thicker wall assemblies.
Can this hanger be installed with a power nailer?
Yes. The Simpson DGHT is the first fire wall hanger specifically designed for installation 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, offering flexibility on the job site.
What drywall thickness does the DGHT2.56/20 accommodate?
The top-flange design provides space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete, making it well suited for fire wall assemblies that require this common drywall configuration.
What is the minimum wall size required for back-to-back installation?
The innovative top-flange design of the DGHT2.56/20 supports back-to-back installation on walls that are 2x6 or larger in dimension. The two-hour fire rating applies to walls that are 2x4 or thicker.
