Deck Tension Tie DTT Kit, Simpson Strong-Tie, Deck to House Lateral Load Connection, Includes (4) DTT1Z and Fasteners

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 hold-down 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. The DTT1Z is available in a kit (DTT1Z-KT) that includes four DTT1Z connectors, four Strong-Drive® SDWH™ Timber-Hex HDG screws (SDWH27800G) and (26) #9 x 1 1/2" Strong-Drive SD Connector screws.
