Description

The Strong-Tie DTT tension ties are safe, cost-effective connectors designed to meet or exceed code requirements for deck construction. The DTT1Z-KT is a kit that includes 4 DTT1Z connectors and all of the necessary SD connector screws and HDG SDWH timber screws. 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 lbs. lateral load connection to the house at four locations per deck.

Use them on every deck

Great tension ties. I use them on every deck I build

Worked for me

I used these to bring my deck up to code (4 tie-points to the house in addition to the ledger board), and I also used them to reinforce the handrail guard posts. It is strange that Simpson makes two different ties (DTTZ1 and DTTZ2). The DTTZ1 is much cheaper and seems to work just as well. Glad to get my deck sturdy again!

Deck Ties Strengthen the Deck-to-House Connection

Deck ties and deck tie connectors help reinforce the connection between deck framing and the house structure. By tying the deck joists back to the house framing, these connectors help resist lateral movement and reduce the risk of deck separation.
Reliable Deck Tie Connectors for Framing Stability

Deck tie connectors are designed for easy installation with pre-punched holes and compatible fasteners. These deck ties for decks and framing connections allow contractors and builders to reinforce joists without complicated installation. Using the correct deck tension tie connector helps create a stronger and more dependable deck structure.
Engineered for Outdoor Deck Construction

Deck ties and deck tension tie connectors are designed for exterior installations where moisture and treated lumber are common. Many Simpson Strong-Tie deck ties, including models like DTT1Z and DTT2Z, offer corrosion-resistant finish options such as 316 stainless steel, helping protect structural connections from longterm environmental exposure.
