Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2-1/2 in. x 20 in. engineered wood is a patent-pending, load-tested, and fire-rated connector built for multifamily and multilevel Type III residential construction. This top-flange hanger is the first fire wall hanger designed to install with a power nailer, allowing crews to complete framing connections faster before drywall goes up and helping keep projects on schedule. Tested to ASTM E814 and carrying a two-hour fire-resistant rating for use on both sides of the wall, it accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete - making it a dependable solution wherever fire-rated wall assemblies are required.
Key Features
- Power nailer compatible installation - the first fire wall hanger designed for power-driven nails, reducing installation time before drywall and keeping construction timelines on track
- Load tested and code listed for 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails - gives contractors flexible fastening options without sacrificing verified load performance
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01, tested to ASTM E814) - confirms the hanger meets fire-rated assembly requirements for use on both sides of the wall, simplifying code compliance on multifamily projects
- Top-flange design enables back-to-back installation on 2x6 (minimum) walls - supports efficient framing layouts in multilevel residential construction where paired hangers are required
- Space for two layers of 5/8 in. drywall after framing - the hanger accommodates gypsum board installation after structural framing is complete, keeping the construction sequence flexible
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility means the hanger works across a wide range of common framing configurations
- 12-gauge steel with G90 zinc galvanized coating - heavy-gauge construction paired with corrosion-resistant finishing supports long-term durability in demanding job-site conditions
Why This Product
- Purpose-built for fire-rated framing assemblies - unlike standard joist hangers, this connector is specifically engineered and tested for fire wall applications, carrying a verified two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01, so there is no guesswork when fire-rated construction is specified
- Faster installation with a power nailer - as the first fire wall hanger designed for power-nailer use, it removes a common bottleneck before drywall installation, giving crews a practical time advantage on multifamily and multilevel projects
- Engineered for the exact member size with no field modification needed - sized precisely for 2-1/2 in. x 20 in. engineered wood members with a matching 2-9/16 in. seat width, it fits correctly the first time and supports clean, inspection-ready framing connections
- Backed by Simpson testing and technical support - load-tested performance data, code listings, and expert technical support mean contractors and engineers have the documentation they need to specify and install with confidence on complex residential fire wall projects
