The Simpson Strong-Tie DGHT Top-Flange Fire Wall Hanger (Model DGHT1.81/16) is a patent-pending, load-tested hanger engineered specifically for 1-3/4 in. x 16 in. engineered wood joists. Designed for multifamily, multilevel Type III residential construction, this innovative hanger carries a two-hour fire rating tested to ASTM E814 and is fire rated for use on both sides of the wall. As the first fire wall hanger built to install with a power nailer, it saves significant time before drywall hanging, helping keep construction projects on schedule. The top-flange design allows two layers of 5/8-in. gypsum board to be slipped into place after framing is complete, streamlining the entire build sequence.

Frequently Asked Questions

What is the fire rating of the Simpson DGHT1.81/16, and how was it tested?

The DGHT1.81/16 carries a two-hour fire-resistant rating. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. The rating is certified under Intertek Design No. SST/WPCF 120-01.

What joist size is the DGHT1.81/16 designed to support?

This hanger is specifically engineered for 1-3/4 in. x 16 in. engineered wood joists, with a seat width of 1-13/16 in.

Can the DGHT1.81/16 be installed with a power nailer?

Yes. The DGHT 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 or hand-installed nails (0.148 in. diameter), allowing faster installation before drywall is hung.

How does the top-flange design accommodate drywall?

The innovative top-flange design provides dedicated space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This allows the hanger to be fully installed during framing, and drywall is added afterward without obstruction, streamlining the construction workflow.
