The Simpson Strong-Tie DTT1Z Deck Tension Tie provides a less invasive approach for attaching a new deck to a home or retrofitting an existing deck to current code standards. This tension tie addresses a 2015 International Residential Code provision (section R507.2.4) that now allows four 750 lb. lateral connectors to be fastened to framing in the house with a lag screw. This provision is an alternative to using two 1,500 lb. lateral connections from the deck to the floor joists within the house.
The DTT1Z is specifically designed to comply with this new code detail that permits the lateral connection from the deck joists to be made to top plates, studs, or headers within the supporting structure. This eliminates the need to access the floor joists inside the house. The DTT1Z fastens to the narrow or wide face of a single 2x with Strong-Drive® SD Connector screws. The new Strong-Drive® SDWH Timber-Hex HDG screw with an integral washer attaches the tension tie to the supporting structure. ZMax® coating offers additional corrosion protection for
exterior and preservative-treated wood applications.

ZMax® Galvanized Coating Information
ZMax® Coating is a thicker coating (galvanized per ASTM A653 with a G185 coating) than the standard hot-dip galvanized coating (galvanized per ASTM A653 with a G90 coating). This thicker coating is available on select Simpson Strong-Tie connectors. Due to this increased galvanized thickness these connectors would be expected to have a longer service life than standard galvanized connectors.
Level of Corrosion Resistance: Medium
