Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2-1/2 in. x 9-1/2 in. engineered wood is a patent-pending joist connector purpose-built for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Load tested and carrying a two-hour fire-resistant rating, this hanger is the first fire wall hanger engineered to accept a power nailer, reducing installation time before drywall goes up and helping keep demanding construction schedules on track. Its innovative top-flange design accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, and it is rated for use on both sides of the wall. Made in the United States from 12-gauge G90 galvanized steel and backed by Simpson expert service and technical support, the DGT hanger is a reliable, code-listed solution for fire wall joist connections.
Key Features
- Power nailer compatible installation - accepts 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails, so crews can fasten the hanger quickly before drywall is hung, reducing labor time and keeping projects on schedule
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01, tested to ASTM E814) - provides code-compliant fire protection on both sides of the wall, meeting the demands of multifamily and multilevel Type III residential assemblies
- Top-flange design for back-to-back installation on 2x6 (minimum) walls - allows two hangers to be set back-to-back without conflict, simplifying layout on fire wall framing projects
- Space for two layers of 5/8 in. gypsum board after framing - drywall slides into place once framing is complete, eliminating the need to coordinate hanger installation around board hanging
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility gives specifiers and framers flexibility across a range of fire wall assembly designs
- 12-gauge steel construction with G90 galvanized coating - heavy-gauge steel delivers the structural strength required for load-tested joist connections, while the zinc galvanized finish resists corrosion over the life of the structure
Why This Product
- The first fire wall hanger designed for power nailer use - no other design detail saves jobsite time the way power nailer compatibility does; crews can drive fasteners before drywall is installed, keeping multifamily construction timelines on track without sacrificing code compliance
- Fully load tested and fire rated for both sides of the wall - the combination of ASTM E814 testing and a two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01 means the hanger meets the fire wall performance requirements that Type III residential projects demand, with documentation to back it up
- Engineered specifically for fire wall assemblies with drywall clearance built in - the top-flange configuration reserves space for two layers of 5/8 in. gypsum board, so the hanger and the fire-rated wall system work together by design rather than as an afterthought
- Made in the United States by Simpson and backed by expert technical support - domestic manufacturing and the backing of Simpson service give contractors and specifiers confidence in product availability, quality consistency, and access to knowledgeable support when questions arise on the job

Frequently Asked Questions
What fire rating does the DGT2.56/9.5 carry, and how was it tested?
The DGT2.56/9.5 carries a two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested in accordance with ASTM E814 and is fire rated for use on both sides of the wall. The two-hour fire rating applies to 2x4 or thicker walls.
Can this hanger be installed with a power nailer?
Yes. The DGT Top-Flange Fire Wall Hanger is the first fire wall hanger specifically designed for power nailer installation. It is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails, as well as hand-installed nails, providing flexibility on the jobsite.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design provides space for two layers of 5/8 in. gypsum board (drywall) to be slipped into place after framing is complete. This means drywall does not need to be installed before the hanger, simplifying sequencing on the jobsite. The design also supports back-to-back installation on 2x6 (minimum) walls.
What fasteners are required to install the DGT2.56/9.5?
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. Always follow the published load tables and installation instructions to ensure code compliance.
