The Simpson DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered specifically for 5-1/4 in. x 20 in. engineered wood members used in multifamily and multilevel Type III residential construction. Built by Simpson to carry a two-hour fire rating tested in accordance with ASTM E814, this top-flange hanger is fire rated for use on both sides of the wall - making it a reliable choice for fire wall assemblies that must meet strict code requirements. As the first fire wall hanger designed to install with a power nailer, it helps crews move faster before drywall goes up, keeping framing schedules on track without sacrificing fire-rated performance.

Key Features

• Compatible with power-driven or hand-installed nails (1-1/2 in. and 2-1/2 in.) - loads tested and code listed for both fastener lengths and installation methods, giving crews flexibility on the job site without compromising code compliance.
• Two-hour fire rating on 2x4 or thicker walls - tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, so the hanger meets fire-rated wall assembly requirements on both sides of the wall.
• Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hangers to be set simultaneously, simplifying framing in multifamily and fire wall applications where mirrored installations are common.
• Space for two layers of 5/8-in. drywall after framing is complete - the hanger accommodates gypsum board installation after the structure is up, so drywall crews are not working around the fastening process.
• Made from 10-gauge steel with a G90 zinc galvanized finish - the heavy-gauge construction delivers the load capacity required for large engineered wood members, while the galvanized coating provides corrosion resistance in exposed framing environments.

Why This Product

• Built to meet fire wall code requirements from day one - with a two-hour fire rating tested to ASTM E814 and an Intertek certification, this hanger is purpose-built for fire-rated assemblies in multifamily and Type III residential projects, reducing the guesswork around code compliance.
• The first fire wall hanger designed for power nailer installation - this patent-pending design lets installers use a power nailer before drywall goes on, cutting labor time significantly compared to hangers that require slower hand-nailing methods during fire wall framing.
• Designed around the full framing workflow - the top-flange configuration and built-in clearance for two layers of 5/8-in. gypsum board mean the hanger works with the construction sequence rather than against it, avoiding rework and scheduling delays.
• Sized and rated for large engineered wood members - with a 5-1/4 in. x 20 in. joist seat and 10-gauge steel construction, this hanger is matched to the heavy engineered lumber spans common in multilevel residential buildings, where undersized hardware is not an option.
