The new series includes three models of top-flange hangers that connect floor joists to the wood wall and feature enough space for two layers of 5/8″ drywall to be installed later. The completed fire wall assembly remains continuous from floor to floor. All three fire wall hangers have been tested according to ASTM E814 standards to verify that the hangers do not reduce the two-hour assembly rating, and therefore each of the DG hangers received F (flame) and T (temperature) ratings for use on either or both sides of a wall.
“With the increasing popularity of Type III multi-story wood construction, it’s more important than ever to ensure that these large, multi-family buildings are constructed with the safest, strongest, most rigorously tested products,” said Sam Hensen, vice president and general manager of Connectors at Simpson Strong-Tie. “Specifying and installing this product will help our customers streamline their workflows on the construction site while adhering to the strict code requirements for load and fire safety.”
