Frequently Asked Questions

What is the RPS28 designed to repair?

The RPS28 is a retrofit strap tie specifically designed for wood members where pipes and ducts have been installed, such as when a top plate or sole plate has been cut or notched to accommodate HVAC lines or plumbing. It restores the structural connection of the framing member.

Which building codes does the RPS28 comply with?

The RPS28 meets IBC (International Building Code), IRC (International Residential Code), and City of Los Angeles code requirements for HVAC and pipes in walls, making it suitable for permitted repair and construction projects in a wide range of jurisdictions.

How does the RPS28 install, and what fasteners are required?

The RPS28 is installed on the narrow face of a 2x lumber member using its staggered nail pattern. It requires (12 - 16) 0.162 in. x 2-1/2 in. nails for proper installation. The staggered pattern helps distribute load and minimizes the risk of wood splitting.

What corrosion protection does the RPS28 offer?

The RPS28 features a G90 zinc galvanized coating, which provides a robust level of corrosion resistance suitable for standard interior framing repairs and connections. For applications requiring additional corrosion protection, such as at sill plates, the ZMAX-coated variant (RPS28Z) is recommended instead.
