The Simpson Strong-Tie DGHT2.37/18 DGHT Top-Flange Fire Wall Hanger by Simpson Strong-Tie is engineered for multifamily, multilevel Type III residential construction requiring a dependable, code-compliant fire wall connection. Designed for 2-5/16 in. x 18 in. engineered wood joists, this patent-pending hanger delivers a two-hour fire rating and is the first fire wall hanger designed to install with a power nailer - saving critical time on the jobsite before drywall installation begins.
