Product Description
The Simpson DGHT Top-Flange Fire Wall Hanger is a load-tested, code-listed hanger engineered for 3 1/2 in. x 18 in. engineered wood joists in multifamily, multilevel Type III residential construction. This patent-pending hanger carries a two-hour fire-resistant rating and is the first fire wall hanger designed to install with a power nailer, helping keep framing crews on schedule before drywall begins. Its innovative top-flange design allows two layers of 5/8 in. gypsum board to slip into place after framing is complete, and it has been tested to ASTM E814 for fire-rated performance on both sides of the wall.
Key Features
- Power nailer compatible, loads tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - eliminates the need to hand-nail every fastener, significantly reducing installation time on large framing projects.
- Two-hour fire-resistant rating applies to 2x4 or thicker walls - meets fire separation requirements for multifamily and multilevel Type III residential assemblies on both sides of the wall.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies fire wall framing by allowing paired hangers to be set simultaneously without interference.
- Space for two layers of 5/8 in. drywall after framing is complete - lets crews finish structural framing first and hang gypsum board later, keeping trades sequenced efficiently.
- Intertek certified under Design No. SST/WPCF 120-01, tested to ASTM E814 - provides the third-party documentation inspectors and code officials require for fire-rated wall assemblies.
- Made from 10-gauge steel with a Zinc Galvanized G90 finish - delivers structural rigidity and corrosion resistance suited for long-term performance in residential construction environments.
Why This Product
- The first fire wall hanger built for power nailer installation - this patent-pending design removes a longstanding jobsite bottleneck, letting crews drive fasteners faster and keep drywall schedules on track without sacrificing load-tested performance.
- Certified two-hour fire rating on both sides of the wall - with ASTM E814 testing and Intertek certification already in hand, this hanger simplifies plan approval and inspection sign-off for fire-rated residential assemblies.
- Top-flange geometry that works with finished drywall assemblies - because the hanger accommodates two full layers of 5/8 in. gypsum board slipped in post-framing, it eliminates the coordination problems that arise when hangers and drywall compete for the same space.
- American-made 10-gauge steel construction with G90 galvanization - the heavy-gauge build and corrosion-resistant coating mean the hanger holds up through construction exposure and delivers the structural integrity that load-tested, code-listed fire wall connections demand.

Frequently Asked Questions
What fire rating does the Simpson DGHT3.62/18 carry, and how is it certified?
The DGHT3.62/18 carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is certified under Intertek Design No. SST/WPCF 120-01. The two-hour fire rating applies to 2x4 or thicker walls and is valid for use on both sides of the wall.
What nail sizes are approved for installing the DGHT3.62/18?
The hanger is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails with a shank diameter of 0.148 in. The installation pattern calls for (6) nails in the top flange, (2) or (4) nails in the face depending on nail length, and (6) nails in the joist.
How does the top-flange design benefit fire wall construction?
The innovative top-flange design allows the hanger to be installed with a power nailer before drywall is hung. After framing is complete, two layers of 5/8-in. gypsum board can be slipped into the space provided by the hanger, streamlining the construction sequence and helping keep projects on schedule.
What steel gauge and corrosion protection does the DGHT3.62/18 feature?
The hanger is made from 10-gauge steel and is finished with a Zinc Galvanized G90 coating, providing reliable corrosion resistance for demanding construction environments.
