Oatey® Suspension Pipe Clamps are designed to secure copper, PEX and CVPC piping to joists and rafters or through studs. Made of corrosion resistant polypropylene, these suspension clamps eliminate contact between the pipe and framing surface, reducing water line noise. A ribbed design allows for faster cooling and pipe expansion and contraction. Oatey products have earned the trust of plumbing professionals for over 100 years.
