Simpson Strong-tie DTT1Z Deck Tension Tie

Product Description

The SIMPSON STRONG-TIE DTT1Z is a deck tension tie connector designed for attaching decks to a home structure without requiring interior floor joist access. It serves a dual purpose: meeting code requirements for deck ledger connections and functioning as a light-duty holdown for shearwall and braced wall panel applications. The DTT1Z features a 3/4-inch centerline design that allows for a low-profile, less invasive installation. It is installed by contractors, framers, and licensed carpenters working on new deck construction or retrofit projects that must meet current building code standards.

The DTT1Z is suited for both new deck builds and retrofit applications where bringing an existing deck up to current code is required. Its design eliminates the need to open up interior framing or access floor joists from inside the structure, reducing labor time and disruption. It also carries a load rating for light-duty shearwall and braced wall panel use, making it a versatile connector for residential wood-frame construction.
