Description

The Simpson Strong-Tie DTT2 Deck Tension Tie with ZMAX coating is engineered to provide a reliable lateral load connection between your deck and the supporting structure. Designed to help resist deck movement caused by wind or seismic forces, the DTT2 plays a critical role in improving overall deck stability and safety.

This model features a corrosion-resistant ZMAX galvanized finish, making it ideal for exterior deck applications exposed to the elements. Each DTT2 includes (8) 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws for secure attachment to deck joists or framing members. When properly installed with a 1/2" diameter threaded rod or anchor bolt into the supporting structure, the DTT2 helps meet code requirements for deck lateral load connections.

Compact, durable, and easy to install, the DTT2 is a smart solution for strengthening residential deck construction and providing added peace of mind.

DTT/DJT14Z Deck Joist Ties

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.
