The Simpson Strong-Tie Outdoor Accents DTT1PC Deck Tension Tie is a 14-gauge steel structural connector engineered to create a code-compliant deck-to-house attachment without requiring access to interior floor joists. Finished in ZMAX galvanized steel with a stylish black powder coat, this deck tie is built for both new deck construction and retrofit projects where a secure, reliable lateral load connection is needed. The DTT1PC is designed for use with single or double 2x lumber members and installs on either the narrow or wide face of a single nominal 2x member, giving builders and homeowners flexible installation options on a wide range of framing configurations.

Key Features

• Code-compliant deck-to-house attachment without interior floor joist access - makes it possible to secure a deck to a home from the exterior, saving time and preserving finished interior spaces during both new builds and retrofits.
• Installs on the narrow or wide face of a single nominal 2x member - provides installation flexibility so the connector adapts to different framing orientations and job-site conditions.
• Ideal for new construction and retrofits - a versatile solution that works whether you are building a deck from scratch or reinforcing an existing structure to meet current standards.
• Accepts a 3/8 in. bolt, anchor bolt, lag screw (with washer), or Strong-Drive SDWH screw for structural anchorage - compatibility with multiple fastener types lets installers use the hardware best suited to the substrate and project requirements.
• Made from 14-gauge steel - a proven material thickness that delivers the structural integrity required for load-bearing deck connection applications.
• ZMAX galvanized with a black powder-coat finish - the dual-layer protection provides superior corrosion resistance for outdoor exposure, while the black finish delivers a clean, attractive look that complements Outdoor Accents hardware.

Why This Product

• No interior access required - the DTT1PC attaches from outside the structure, eliminating the need to open up finished walls or ceilings to reach interior floor joists, which reduces labor and disruption on retrofit projects.
• Dual-layer corrosion protection built for outdoor environments - ZMAX galvanized steel combined with a black powder coat means this deck tension tie resists moisture and the elements, reducing the risk of premature corrosion on exposed deck framing.
• Works with a range of structural fasteners - by accepting a 3/8 in. machine bolt, anchor bolt, lag screw, or Strong-Drive SDWH Timber-Hex HDG screw, the DTT1PC fits into the fastening strategy already planned for most deck projects without requiring specialty hardware.
• Made in the United States by Simpson Strong-Tie - the DTT1PC is manufactured domestically and backed by the engineering expertise of one of the construction industry's most recognized connector brands.
