Product Description
Simpson Strong-Tie® DTT™ 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. The 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.
