Frequently Asked Questions

What fire rating does the DGT28 carry, and how was it tested?

The DGT28 carries a two-hour fire-resistant rating. It has been tested in accordance with ASTM E814 and is 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 walls.

Can the DGT28 be installed with a power nailer?

Yes. The DGT28 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 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 provides space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This allows for efficient sequencing of framing and drywall work without requiring modifications to the hanger or framing assembly.

What is the minimum wall thickness required for back-to-back installation of the DGT28?

The DGT28's top-flange design supports back-to-back installation on walls that are 2x6 (minimum) in size. The two-hour fire rating applies to 2x4 or thicker walls in single-side applications.
