The Simpson 22-5/16" Galvanized Retrofit Strap Tie is a purpose-built repair strap from Simpson Strong-Tie, engineered to reinforce wood framing members that have been cut or notched to accommodate pipes, HVAC ducts, and other mechanical installations. Constructed from 16-gauge steel with a G90 zinc galvanized finish, this retrofit plate strap fits cleanly on the narrow face of a standard 2x member and meets IBC, IRC, and City of Los Angeles code requirements for HVAC and pipes in walls - making it a reliable solution for both light repairs and heavy-duty structural connections.

Key Features

• Repair strap for wood members where pipes and ducts are installed - directly addresses one of the most common framing challenges in residential and commercial construction, restoring structural integrity after notching or cutting.
• Fits on the narrow face of a 2x member - the 1 1/2 in. width aligns precisely with standard dimensional lumber so the strap seats flush without overhanging, enabling a clean and code-compliant installation.
• Versatile fastening applications - suitable for use where top plates or sole plates are cut, at wall intersections, or as a ridge tie, giving contractors and builders a single strap that handles multiple connection scenarios.
• Staggered nail pattern - distributes load evenly across the connection, supporting proper structural performance and simplifying fastener placement during installation.
• 16-gauge steel construction - delivers the structural strength needed for both repair and heavy-duty framing applications without adding unnecessary bulk.
• G90 zinc galvanized finish - provides corrosion resistance suited to the demanding environments where wall framing straps are typically installed, helping the connection maintain its integrity over time.

Why This Product

• Code-accepted for HVAC and pipe installations - the RPS22 meets IBC, IRC, and City of Los Angeles requirements for HVAC and pipes in walls, so contractors can install it with confidence on permitted projects without seeking alternative solutions.
• Designed specifically for retrofit and repair work - where generic straps may not fit or perform correctly, this strap is purpose-engineered for wood members that have been compromised by pipe and duct cutouts, making it the right tool for the job rather than a workaround.
• Simple, repeatable installation on standard lumber - the narrow-face fit on 2x members and staggered nail pattern mean installers can work efficiently and consistently across multiple openings or wall locations without custom fitting or modification.
• Durable G90 galvanized protection from a trusted brand - Simpson Strong-Tie's G90 zinc galvanized coating guards against corrosion, and the strap is made in the United States, reflecting the quality standards that framing and structural hardware professionals rely on.
