Whether you’re building a brand new deck or retrofitting an existing one, concerns about the strength and safety of your deck can be a significant source of tension. Other than the quality of the wood itself, how the wood members of a deck are connected to each other and to the adjacent structure is the most important part of the deck. Connections that don’t meet code requirements or that have become loose, corroded or decayed over time, compromise a deck’s strength and safety.

The DTT1Z 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 current deck code-compliant, the DTT1Z can be used as a tension-tie to satisfy the 2015 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 (4) DTT1Z connectors, (4) Strong-Drive® SDWH Timber-Hex HDG screws and (26) SD #9 x 1 1/2″ screws.
The DTT1Z fastens to the narrow or wide face of a single 2x with Simpson Strong-Tie® Strong-Drive SD Connector screws or nails and accepts a 3/8″ machine bolt, anchor bolt or lag screw (washer required) or can be installed with the Strong-Drive SDWH Timber-Hex HDG screw with an integral washer.
