The Simpson DGT2.37/20 carries a two-hour fire-resistant rating, tested in accordance with ASTM E814. It is fire rated for use on both sides of the wall and holds Intertek Design No. SST/WPCF 120-01. The two-hour fire rating applies to 2x4 or thicker walls.

Can this hanger be installed with a power nailer?

How does the top-flange design accommodate drywall installation?

The 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 without obstructing subsequent drywall application, keeping the construction schedule on track.
