Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger by Simpson is purpose-built for multifamily, multilevel Type III residential construction where fire wall compliance is non-negotiable. This patent-pending, load-tested hanger earns a two-hour fire rating - tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01 - and is rated for fire-resistant use on both sides of the wall. Its innovative top-flange design is the first of its kind engineered to install with a power nailer, dramatically reducing installation time before drywall goes up and helping keep framing schedules on track. The hanger accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, making it a practical, code-conscious choice for fire wall assemblies in engineered wood framing systems.
Key Features
- Power nailer compatible - the first fire wall hanger designed for it - eliminates the slowdown of hand-nailing before drywall installation, keeping construction schedules moving on busy multifamily job sites.
- Load 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 fastening method that fits their workflow without sacrificing code compliance.
- Two-hour fire rating applicable to 2x4 or thicker walls - satisfies fire wall assembly requirements for a wide range of Type III residential framing configurations on both sides of the wall.
- Top-flange design supports back-to-back installation on 2x6 (minimum) walls - enables paired hanger placement at fire wall assemblies without conflict, simplifying layout in multilevel residential framing.
- Accommodates two layers of 5/8 in. drywall inserted after framing is complete - the hanger does not interfere with gypsum board installation, preserving the assembly sequence and maintaining the integrity of the fire-rated wall system.
- Made from 10-gauge steel with a G90 zinc galvanized finish - provides the structural strength and corrosion resistance demanded in long-term residential construction applications.
- Intertek certified under Design No. SST/WPCF 120-01 - offers third-party verified fire performance documentation that supports plan review and code approval.
Why This Product
- A fire wall hanger built around job site efficiency - as the first fire wall hanger designed for power nailer installation, it removes a traditional bottleneck in the framing-to-drywall sequence, helping crews maintain momentum on multifamily and multilevel residential projects.
- Comprehensive fire rating backed by independent testing - the two-hour fire-resistant rating, verified to ASTM E814 and certified by Intertek, provides the documented code compliance that architects, inspectors, and general contractors require for fire wall assemblies.
- Designed for the full fire wall assembly, not just the structural connection - by reserving space for two layers of 5/8 in. gypsum board and supporting back-to-back placement on 2x6 minimum walls, this hanger is engineered around the complete wall system, not just the joist.
- Trusted Simpson engineering produced domestically - manufactured in the United States from 10-gauge steel with a G90 galvanized coating, this hanger reflects the material quality and load-tested performance that structural framing professionals depend on for fire-rated construction.
