The Simpson DGT Top-Flange Fire Wall Hanger from Simpson is a patent-pending, load-tested joist hanger engineered for multifamily and multilevel Type III residential construction where two-hour fire-rated wall assemblies are required. Its innovative top-flange design holds space for two layers of 5/8 in. gypsum board to be slipped in after framing is complete, and it is the first fire wall hanger built to work with a power nailer - keeping crews moving and projects on schedule. Tested to ASTM E814 and carrying a two-hour fire-resistant rating for use on both sides of the wall, this hanger is sized for 2-5/16 in. x 9-1/2 in. engineered wood members and made from 12-gauge steel with a G90 zinc galvanized finish.

Key Features

• Power nailer compatible installation - the first fire wall hanger designed for power-driven nails, reducing installation time before drywall and helping keep construction schedules on track
• Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - meets fire-rated assembly requirements on both sides of the wall, supporting code compliance in Type III residential construction
• Tested to ASTM E814 - independently verified performance gives engineers and inspectors documented confidence in the assembly
• Top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hangers to be set during framing without blocking drywall installation
• Space for two layers of 5/8 in. drywall after framing - eliminates the need to coordinate hanger placement around gypsum board, simplifying sequencing on the job site
• Code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - gives installers flexibility to use the fastener length that suits the specific wall assembly
• Two-hour rating applies to 2x4 or thicker walls - broad wall thickness compatibility makes the hanger practical across a wide range of framing configurations
• 12-gauge steel with G90 zinc galvanized finish - heavy-gauge construction paired with corrosion-resistant coating supports long-term durability in the assembly

Why This Product

• Designed to speed up fire wall framing - as the first fire wall hanger engineered for power nailer use, it allows crews to set hangers faster before drywall goes up, reducing labor time at a stage of construction where delays are costly
• Fire-rated on both sides, tested to a recognized standard - the two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01 and ASTM E814 testing provide the documented performance that multifamily and multilevel projects demand from every component in a fire wall assembly
• Engineered specifically for fire wall assemblies, not adapted from a generic hanger - the top-flange configuration accommodates back-to-back placement and reserves room for two layers of 5/8 in. gypsum board, so the hanger works with the full assembly rather than around it
• Wide size range with consistent design logic - the DGT line spans multiple member sizes, making it straightforward to specify and source the correct hanger for different joist dimensions without switching to a different hanger family or installation approach
