Available in many lengths, widths and thicknesses, straps can be used on the wide or narrow face of lumber for light repairs or heavy-duty projects. Many straps are designed to be used back-to-back on a piece of lumber without fastener interference. The RPS meets IBC, IRC and City of Los Angeles code requirements for HVAC and pipes in walls.
