The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested hanger engineered specifically for 1-3/4 in. x 16 in. engineered wood joists in multifamily, multilevel Type III residential construction. This fire wall hanger carries a two-hour fire-resistant rating tested to ASTM E814 and is fire rated for use on both sides of the wall, making it a reliable choice wherever code-compliant fire-rated framing assemblies are required. As the first fire wall hanger designed to install with a power nailer, it eliminates a significant bottleneck before drywall hanging and helps keep construction timelines on track. The top-flange design accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, streamlining the entire build sequence.

Key Features

• Loads tested and code listed for 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails - gives contractors flexibility to use a power nailer or install by hand without sacrificing code compliance.
• Two-hour fire-resistant rating applies to 2x4 or thicker walls - meets fire wall assembly requirements on a wide range of wall configurations, reducing the risk of costly redesigns.
• Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies paired hanger installation at shared fire walls, cutting layout and labor time on multifamily projects.
• Space for two layers of 5/8 in. drywall after framing - allows gypsum board to be installed after the structure is framed, keeping trades from working around each other and improving job site workflow.
• Two-hour Fire-Resistant rating certified under Intertek Design No. SST/WPCF 120-01 - provides a third-party verified, code-ready rating that supports plan review and inspection approvals.
• Made from 10-gauge steel - delivers the structural strength needed for heavy engineered wood framing members in high-load residential applications.
• Zinc Galvanized, G90 finish - provides corrosion resistance to help the hanger hold up through construction exposure and in demanding building environments.

Why This Product

• The first fire wall hanger built for power nailer installation - this patent-pending design removes a manual nailing bottleneck from the framing process, saving measurable time before drywall can begin and helping multifamily projects stay on schedule.
• Certified two-hour fire rating on both sides of the wall - tested to ASTM E814 and listed under Intertek Design No. SST/WPCF 120-01, this hanger gives builders and inspectors confidence that the fire wall assembly meets code on both faces without requiring supplemental hardware.
• Top-flange design simplifies the framing-to-drywall transition - by allowing two layers of 5/8 in. gypsum board to slide in after framing is complete, the hanger keeps the construction sequence clean and reduces interference between framing and drywall crews.
• Versatile nail specification supports field conditions - acceptance of both 1-1/2 in. and 2-1/2 in. nails, whether power-driven or hand-installed, means installers can work with the fasteners and tools already on site without special ordering additional materials.
