Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered specifically for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Designed by Simpson as the first fire wall hanger compatible with power nailer installation, this top-flange hanger carries a two-hour fire-resistant rating tested to ASTM E814 and listed under Intertek Design No. SST/WPCF 120-01, making it a reliable choice for fire wall assemblies that must perform on both sides of the wall. Its innovative design accommodates two layers of 5/8-in. gypsum board slipped into place after framing is complete, keeping construction sequences efficient and projects on schedule.
Key Features
- Compatible with power nailer installation - the first fire wall hanger designed for power-driven nails, reducing installation time before drywall and helping keep multifamily projects on schedule
- Loads tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - gives crews the flexibility to use the fastener size that suits their workflow without sacrificing code compliance
- Two-hour fire-resistant rating tested to ASTM E814 - meets stringent fire wall requirements for Type III residential construction and is rated for use on both sides of the wall
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies framing at fire wall locations and eliminates the need for specialized blocking or custom fabrication
- Space for two layers of 5/8-in. drywall after framing is complete - allows gypsum board to be slipped in after the structure is set, supporting a logical, efficient construction sequence
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility suits a wide range of fire wall assembly designs in residential construction
- Made from 10-gauge steel with G90 zinc galvanized coating - heavy-gauge construction delivers the strength required for engineered wood members, while the galvanized finish provides corrosion resistance for long-term durability
Why This Product
- Purpose-built for fire wall assemblies in multifamily construction - unlike standard joist hangers, the DGHT is specifically load-tested and fire-rated to ASTM E814, giving builders a single product that satisfies both structural and fire-resistance requirements in Type III residential projects
- Power nailer compatibility saves measurable time on the job - as the first fire wall hanger engineered for power-driven fasteners, it eliminates the slow, nail-by-nail hand installation that other fire wall hangers require, keeping framing crews productive before drywall goes up
- Top-flange design streamlines the drywall phase - by reserving space for two layers of 5/8-in. gypsum board to slide in after framing, this hanger removes a common sequencing conflict and reduces the need to coordinate hanger installation around drywall schedules
- Rated on both sides of the wall for maximum design flexibility - the two-hour fire-resistant rating is valid for use on both sides of the wall, making this hanger suitable for a wider range of fire wall assembly configurations without requiring separate products or additional testing documentation

Frequently Asked Questions
What fire rating does the DGHT7.12/11.88 carry, and how was it tested?
The DGHT carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is listed under Intertek Design No. SST/WPCF 120-01. The two-hour fire rating applies to 2x4 or thicker walls and is valid for use on both sides of the wall.
Can this hanger be installed with a power nailer?
Yes. The DGHT is specifically designed as the first fire wall hanger compatible with power nailer installation. 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 job site.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design allows the hanger to be fully installed during framing. After framing is complete, two layers of 5/8-in. gypsum board (drywall) can be slipped into the space provided by the hanger on both sides of the wall, streamlining the workflow and keeping projects on schedule.
What are the minimum wall thickness requirements for back-to-back installation?
The DGHT top-flange design supports back-to-back installation on walls that are a minimum of 2x6 in thickness. The two-hour fire rating applies to walls that are 2x4 or thicker.
