Simpson Strong Tie DTT2Z Deck Tension Tie 20 Pack

Product Description

The SIMPSON STRONG TIE DTT2Z is a deck tension tie engineered to anchor railing posts directly into the deck framing rather than relying on the rim joist alone. Constructed from Zmax material for corrosion resistance, each unit ships with 1.5-inch screws included. The DTT2Z transfers lateral and vertical loads from posts back into the joists, improving load distribution across the deck structure. This fastener meets IRC and IBC standards for handrail and guardrail connections and also satisfies IRC lateral-connection requirements for securing a deck to the house. Licensed contractors and experienced builders install this hardware on both new construction and deck renovation projects.

The DTT2Z is suited for residential deck framing where railing posts must be positively anchored to structural members. By routing load path through the joists, it reduces dependence on rim joist fastening, which is a common point of failure in guardrail assemblies. The tie is appropriate for pressure-treated lumber framing typical in outdoor deck construction. Each package contains 20 individual ties, making it practical for multi-post installations on a single deck run or for contractor stock.

Compatibility

Designed as an OEM-style structural connector for residential wood-framed deck assemblies requiring code-compliant railing post anchorage per IRC and IBC guardrail provisions.

Installation Notes

Installation is typically performed by a licensed contractor or experienced carpenter familiar with IRC and IBC deck framing requirements. Before installation, confirm the deck framing is complete and all structural members are properly fastened. Use only the included or manufacturer-specified fasteners to maintain load-rated performance. Follow local building department requirements, as inspection and permits may be required for deck structural work.
