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. Sized for 1-3/4 in. x 11-7/8 in. engineered wood members, it carries a two-hour fire-resistant rating tested to ASTM E814 and is rated for use on both sides of the wall. Its innovative top-flange design is the first of its kind built to install with a power nailer, letting framing crews complete installations faster and keep projects on schedule before drywall goes up.
Key Features
- Power nailer compatible - first fire wall hanger of its kind - installs with a power nailer using 1-1/2 in. or 2-1/2 in. nails, eliminating the slowdowns of hand-only installation and helping crews stay on schedule.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - provides code-compliant, independently verified fire protection for use on both sides of a fire wall assembly.
- Tested to ASTM E814 and code listed - gives builders, inspectors, and project managers confidence that the hanger meets rigorous fire resistance standards for residential fire wall applications.
- Top-flange design for back-to-back installation on 2x6 (min.) walls - allows two hangers to be installed directly opposite each other, simplifying layout and reducing framing complexity in multifamily builds.
- Accommodates two layers of 5/8 in. drywall - the open top-flange leaves space for dual gypsum board layers to slip into place after framing is complete, keeping the workflow in the correct sequence.
- Two-hour fire rating applies to 2x4 or thicker walls - offers broad compatibility with standard wall framing dimensions found in Type III residential construction.
- Made from 12-gauge steel with G90 zinc galvanized coating - delivers the structural strength and corrosion resistance required for long-term performance in demanding construction environments.
Why This Product
- Built for the pace of multifamily construction - as the first fire wall hanger designed for power nailer installation, this Simpson hanger cuts framing time compared to hand-nail-only alternatives, a direct advantage on high-unit-count residential projects where schedule pressure is constant.
- Independently rated and code listed for fire wall assemblies - the two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01, tested to ASTM E814, means this hanger arrives with the documentation inspectors and building officials require, reducing approval friction on the job site.
- Simplifies sequencing with drywall-ready clearance - the top-flange configuration holds space for two layers of 5/8 in. gypsum board, so framing can be fully completed before drywall crews begin, keeping trades from working over one another.
- Made in the United States and backed by Simpson technical support - the hanger is manufactured domestically and supported by expert service resources, giving contractors a reliable supply chain and a knowledgeable resource when project-specific questions arise.
