SIMPSON ITT WEBWOOD HANGER - The ITTM masonry-to-wood connector can be directly embedded into a grouted block wall. It can also be installed on top of a masonry or concrete wall using Titen screws. The offset seat feature allows better joist bearing positioning. Joist top flanges are laterally restrained by the side of the hanger, eliminating the need for web stiffeners. The I-joist manufacturers may require web stiffeners. Material: ITTM—12 gauge top flange and 18 gauge stirrup; ITT—18 gauge; MIT, HIT—16 gauge. Finish: Galvanized.
