Simpson Strong-Tie Deck Tension Tie, Kit, ZMAX®
DTT tension ties are safe, cost-effective connectors designed to meet or exceed code requirements for deck construction. These versatile DTT connectors are also load rated as a holdown for light-duty shearwalls and braced-wall panel applications. For new construction or to make an existing deck code-compliant, the DTT1Z can be used as a tension tie to satisfy the 2015, 2018 and 2021 IRC provision for a 750 lb. lateral load connection to the house at four locations per deck. This code detail permits the lateral connection from the deck joists to be made to top plates, studs or headers within the supporting structure, which eliminates the need to access to the floor joists inside the home.
