The Simpson Strong-Tie DGHT Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered specifically for multifamily, multilevel Type III residential construction. Designed to support 1-3/4 in. x 9-1/2 in. engineered wood members, this innovative hanger carries a two-hour fire rating and is the first fire wall hanger built to install with a power nailer - saving critical time on the jobsite before drywall goes up. Tested to ASTM E814 standards and fire rated for use on both sides of the wall, the DGHT keeps construction projects on schedule without sacrificing code compliance or structural integrity.

Frequently Asked Questions

What fire rating does the DGHT1.81/9.5 carry, and how was it tested?

The DGHT Top-Flange Fire Wall Hanger 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 rating applies to use on both sides of the wall with 2x4 or thicker wall assemblies.

Can this hanger be installed with a power nailer?

Yes. The DGHT is the first fire wall hanger specifically 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, providing flexibility on the jobsite.

How does the top-flange design accommodate drywall installation?

The top-flange design allows the hanger to be fully installed during framing, leaving space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This sequencing helps maintain construction schedules without compromising the fire wall assembly.

What is the minimum wall thickness required for back-to-back installation?

The DGHT's innovative top-flange design supports back-to-back installation on walls that are 2x6 or thicker (minimum). The two-hour fire rating applies to 2x4 or thicker walls, making the hanger versatile for a range of fire wall framing assemblies.
