Mitek TFI top mount hangers are engineered for I-Joist to header applications. These hangers offer full lateral support of the I-Joist top chord, eliminating the need for web stiffeners in most applications. The raised dimple nailing guides help assure correct 45° nailing into the I-Joist bottom flange. The TFIs feature the patented Seat Cleat that allows for quick, positive seating. The Seat Cleat will hold the I-Joist in place, eliminating spring back during nailing in the bottom flange. All TFI hangers have a G90 galvanizing finish for improved corrosion resistance. Mitek connectors are designed for code compliance, easy installation with commonly-available fasteners, and high performance. Material: Steel.
