Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested connector engineered for multifamily and multilevel Type III residential construction where two-hour fire-resistant performance is required at the framing stage. Designed as the first fire wall hanger compatible with power nailer installation, it eliminates time-consuming hand-nailing before drywall goes up, keeping framing crews on schedule. The top-flange configuration accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete, and the hanger has been tested per ASTM E814 for a two-hour fire-resistant rating on both sides of the wall, holding Intertek Design No. SST/WPCF 120-01. Built from 12-gauge steel with a G90 zinc galvanized finish, this hanger is sized for 3-1/2 in. x 22 in. engineered wood members.
Key Features
- Power nailer and hand-nail compatible - load tested and code listed for 1-1/2 in. and 2 1/2 in. power-driven or hand-installed nails, giving crews flexibility to use the tools already on site without slowing the framing schedule
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - tested per ASTM E814 and rated for use on both sides of the wall, satisfying fire separation requirements for Type III residential projects without additional field verification
- Two-hour rating applies to 2x4 or thicker walls - broad wall-thickness compatibility means the hanger works across common framing assemblies without requiring special construction
- Innovative top-flange design for back-to-back installation on 2x6 minimum walls - allows paired hangers to share a single header without conflicting hardware, simplifying layout at shared fire wall locations
- Accommodates two layers of 5/8 in. drywall after framing is complete - the drywall slips in after structural framing is finished, keeping the construction sequence efficient and reducing interference between trades
- 12-gauge steel construction - provides the structural strength needed for load-tested fire wall connections in demanding multifamily applications
- G90 zinc galvanized finish - corrosion-resistant coating protects the hanger during construction exposure and throughout the service life of the assembly
Why This Product
- The only fire wall hanger built for power nailer installation - this is the first fire wall hanger designed to work with a power nailer, a practical advantage that directly reduces labor time before drywall installation and helps multifamily projects stay on schedule
- Fire rating and structural load testing in a single product - the DGT is both load tested and fire rated, meaning contractors do not need to source separate solutions to satisfy structural and fire-separation requirements at the same connection point
- Engineered specifically for multifamily and Type III residential fire walls - the top-flange design, drywall clearance space, and back-to-back installation capability are purpose-built for the assembly conditions most common in multilevel multifamily construction
- Made in the United States and backed by Simpson technical support - domestic production and manufacturer technical resources give contractors confidence in availability, code documentation, and field support throughout the project

Frequently Asked Questions
What is the fire rating of the DGT3.62/22 hanger, and how was it tested?
The DGT3.62/22 carries a two-hour fire-resistant rating and has been tested in accordance with ASTM E814. It is rated for use on both sides of the wall and holds Intertek Design No. SST/WPCF 120-01. The two-hour 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 designed to install with a power nailer. 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 of the same sizes.
What nail schedule is required to install the DGT3.62/22?
Installation requires (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.
Does the top-flange design allow for drywall installation after framing?
Yes. The innovative top-flange design provides space for two layers of 5/8 in. gypsum board (drywall) to be slipped into place after the framing is complete. This makes it suitable for fire wall assemblies in multifamily and multilevel construction where drywall is installed post-framing.
