The Simpson Strong-Tie DGHT Top-Flange Fire Wall Hanger, Model DGHT3.62/18, 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 delivers a two-hour fire rating and is the first fire wall hanger designed to install with a power nailer, helping keep construction projects on schedule. Its innovative top-flange design accommodates two layers of 5/8-in. gypsum board that 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.

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.
