The Simpson RPS22Z 22-5/16 in. 16-Gauge ZMAX Galvanized Retrofit Strap Tie by Simpson is a purpose-built repair strap designed for wood framing members where pipes and ducts have been installed. Whether reinforcing a sill plate that was cut for HVAC routing or tying wall framing at intersections and ridges, this retrofit plate strap restores structural continuity to wood-frame construction. It meets IBC, IRC, and City of Los Angeles code requirements for HVAC and pipes in walls, giving contractors and builders a code-compliant solution for both new construction and retrofit applications.

Key Features

• Repair strap for wood members where pipes and ducts are installed - directly addresses one of the most common framing repair needs, restoring structural integrity where framing has been cut or notched.
• Fits on the narrow face of a 2x member - installs flush against standard dimensional lumber without requiring additional clearance, keeping the repair clean and accessible in tight wall cavities.
• Fasten where plates or soles are cut, at wall intersections, or as a ridge tie - versatile enough to handle multiple connection types on a single job site, reducing the number of different connectors needed.
• Staggered nail pattern - distributes fastener load across the strap more evenly, helping maximize holding strength and minimize splitting in the wood member.
• Made from 16-gauge steel - provides a sturdy, heavy-duty base material capable of handling the structural demands of framing repair and reinforcement applications.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - outperforms standard galvanized coatings in harsh environments, making this strap a reliable long-term choice wherever pressure-treated lumber or outdoor exposure is a factor.

Why This Product

• Built specifically for retrofit and repair scenarios - unlike general-purpose straps, the RPS22Z is engineered around the real-world problem of weakened framing caused by pipe and duct penetrations, giving you a targeted solution rather than a workaround.
• Meets IBC, IRC, and City of Los Angeles code requirements - eliminates guesswork on inspections and keeps HVAC and plumbing rough-in work compliant without requiring additional hardware or custom engineering.
• ZMAX coating extends service life in demanding conditions - the elevated corrosion protection is especially valuable in exterior walls, crawl spaces, and any application involving treated lumber, where standard coatings can break down prematurely.
• Narrow-face profile fits standard 2x framing without modification - the 1 1/2 in. width is sized to match the narrow face of a 2x member exactly, so installation is straightforward and no trimming or field fabrication is required.

Frequently Asked Questions

What is the RPS22Z designed to repair?

The RPS22Z is specifically designed as a repair strap for wood members where pipes and ducts have been installed. It restores structural integrity to framing members such as top plates and sill plates that have been cut or notched during plumbing or HVAC installation.

What type of fasteners are required to install the RPS22Z?

The RPS22Z should be installed with (12 - 16) 0.162 in. x 2-1/2 in. nails, as specified by Simpson Strong-Tie for proper load transfer and code compliance.

Why is the ZMAX coating important for this strap tie?

The ZMAX galvanized coating provides extra corrosion resistance compared to standard galvanization, making the RPS22Z suitable for exterior environments and applications involving treated lumber, where standard coatings may deteriorate more quickly over time.

Does the RPS22Z meet building code requirements?

Yes. The RPS22Z meets IBC, IRC, and City of Los Angeles code requirements for HVAC and pipes in walls, making it an approved solution for code-compliant retrofit and repair installations in residential and commercial construction.
