Simpson Strong-tie Dtt2z Deck Tension Tie, Z-max, 1-1/2 In. Screws

The Simpson Strong-Tie DTT2Z Deck Tension Tie is a code-compliant connector designed to securely attach deck railing posts to deck framing. Instead of relying solely on the rim joist, this tie anchors the post back into the deck joists, creating a stronger connection that meets or exceeds IRC and IBC code requirements for handrail and guardrail post installations. It also complies with IRC requirements for laterally tying the deck to the house structure.

This tension tie delivers a safe, cost-effective solution for deck construction and is load-rated for light-duty shearwall and braced-wall panel applications. The reinforced tie-back design into the joists provides reliable, long-lasting hold and performance.

Features and Benefits

• Superior Hold: Reinforced tie-back design anchors into deck joists rather than the rim joist alone, delivering stronger lateral support than typical through-bolt installations.
