Frequently Asked Questions

What fire rating does the Simpson DGHT7.12/22 carry, and how was it tested?

The DGHT7.12/22 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 and applies to 2x4 or thicker wall assemblies.

Can this hanger be installed with a power nailer?

Yes. The DGHT is the first fire wall hanger designed specifically for power nailer installation. 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, giving installers flexibility on the job site.

How does the top-flange design accommodate drywall installation?

The innovative top-flange design allows the hanger to be fully installed during framing, after which two layers of 5/8-in. gypsum board (drywall) can be slipped into place. This sequencing saves time and helps keep construction projects on schedule by allowing drywall to be installed after framing is complete without interference from the hanger.

What are the material and corrosion-resistance specifications for this hanger?

The DGHT7.12/22 is manufactured from 10-gauge steel with a G90 zinc galvanized finish, providing reliable corrosion resistance suitable for the demands of residential construction applications.
