Simpson Strong-Tie DTT2SS Deck Tension Tie SS With 1.5-Inch Screws 20 Pieces

The DTT2Z and DTT2SS deck tension ties provide high-strength lateral load connections designed to meet the International Residential Code (IRC) requirement for a 1,500 lb. connection at two locations per deck, as outlined in IRC R507.9.2(1). These connectors are a smart solution for new construction or retrofits, offering reliable performance in securing decks to homes and can also be used to enhance guardrail post safety. With models available in ZMAX and stainless steel, the DTT2 series is built for strength, durability and code compliance in a wide range of environments.

The DTT2Z is a ZMAX-coated tension tie designed to resist lateral forces in deck-to-structure connections. Additionally, the DTT2Z has been tested and evaluated in deck guardrail post applications. It installs on the wide face of a single or double 2x member using included Strong-Drive SDS Heavy-Duty Connector screws and accepts a 1/2-Inch-diameter bolt or anchor bolt. The DTT2Z is also available in configurations with longer SDS screws (DTT2Z-SDS2.5) to achieve higher allowable loads when required.

The DTT2SS offers the same proven performance as the DTT2Z but is made from 316 stainless steel for superior corrosion resistance in coastal, high-moisture and preservative-treated wood applications. It installs using Strong-Drive SDS Heavy-Duty Connector screws (included), and like its ZMAX counterpart, it’s designed to secure the deck to the structure or reinforce guardrail posts for added safety in severe environments. The stainless steel version is ideal for jobsites that demand enhanced durability and long-term protection against corrosion.

Both DTT2Z and DTT2SS connectors provide dependable load-rated solutions for demanding lateral applications—helping contractors meet code, strengthen guardrails, and build safer decks in both standard and corrosive environments.
