Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested, and fire-rated joist hanger built for multifamily and multilevel Type III residential construction. Engineered to carry 1-3/4 in. x 14 in. engineered wood members, this hanger stands out as the first fire wall hanger designed to install with a power nailer - cutting installation time before drywall goes up and helping keep projects on schedule. Its top-flange configuration supports back-to-back installation on 2x6 (minimum) walls while preserving space for two layers of 5/8 in. gypsum board to be slipped into place after framing is complete. Tested to ASTM E814 and carrying a two-hour Fire-Resistant rating (Intertek Design No. SST/WPCF 120-01), it is fire rated for use on both sides of the wall - making it a dependable solution wherever fire-rated wall assemblies are required.
Key Features
- Power nailer compatible installation - the first fire wall hanger code listed for 1-1/2 in. and 2-1/2 in. power-driven nails, so crews can work faster and stay on schedule before drywall begins
- Two-hour Fire-Resistant rating (Intertek Design No. SST/WPCF 120-01, tested to ASTM E814) - meets fire wall assembly requirements on both sides of the wall, supporting compliance on multifamily and multilevel Type III projects
- Top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies fire wall framing where hangers must be installed on opposing sides without conflict
- Built-in clearance for two layers of 5/8 in. drywall - gypsum board slides into place after framing is complete, keeping the workflow sequential and reducing rework
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility gives builders flexibility across common framing configurations
- 12-gauge steel with G90 zinc galvanized finish - heavy-gauge construction paired with corrosion-resistant coating delivers durability in demanding job-site conditions
- Fits 1-3/4 in. x 14 in. engineered wood joists - sized precisely for common engineered lumber dimensions, reducing the need to search for alternative solutions or special configurations
- Made in the United States and widely available - consistent supply and domestic manufacturing help minimize procurement delays on active construction schedules
Why This Product
- Built for fire wall construction from the ground up - unlike standard joist hangers adapted for fire-rated use, this hanger was engineered specifically for fire wall assemblies, with a two-hour Fire-Resistant rating tested to ASTM E814 and verified for use on both sides of the wall
- The first fire wall hanger designed for power nailer installation - this design breakthrough allows faster fastening with 1-1/2 in. or 2-1/2 in. power-driven nails, reducing labor time during framing and helping multifamily projects hit their drywall milestones
- Top-flange geometry solves a real installation challenge - the innovative flange design allows back-to-back hanger placement on 2x6 minimum walls and keeps the joist bay open for two layers of 5/8 in. gypsum board, eliminating the need to coordinate hanger and drywall installation simultaneously
- Backed by Simpson engineering and code compliance documentation - load-tested, code listed, and carrying an Intertek fire rating, this hanger gives contractors and inspectors the documentation needed to move through approvals with confidence on Type III residential fire wall projects

Frequently Asked Questions
What is the fire rating of the DGT1.81/14, and how was it tested?
The DGT1.81/14 carries a two-hour Fire-Resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. The two-hour rating applies to 2x4 or thicker walls.
What nail sizes are approved for installing the DGT1.81/14?
The DGT1.81/14 is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails (0.148 in. diameter). Specifically, install with (6) 0.148 in. x 1-1/2 in. OR 0.148 in. x 2-1/2 in. nails in the top; (2) 0.148 in. x 1-1/2 in. nails OR (4) 0.148 in. x 2-1/2 in. nails in the face; and (6) 0.148 in. x 1-1/2 in. nails in the joist.
Can the DGT1.81/14 be installed using a power nailer?
Yes. The DGT1.81/14 is the first fire wall hanger designed specifically to install with a power nailer. This capability saves installation time before hanging drywall, helping keep construction projects on schedule. It is also compatible with hand-installed nails.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design of the DGT1.81/14 allows two layers of 5/8 in. gypsum board (drywall) to be slipped into place after the framing is complete. It also supports back-to-back installation on 2x6 (minimum) walls, making it well suited for fire wall assemblies in multifamily and multilevel residential construction.
