Suspension type Plastic Pipe Clamps are one of the most common installation accessories. They can be used for support of 3/4" PEX pipes, copper and CPVC pipes across the stud/joist runs. Can also be used as isolators when tubing penetrates a wooden or metal stud. Secured to wood or metal surfaces with appropriate fasteners. Inner grooves of the clamp minimize contact with tubing, eliminate any possible damage to the pipe and reduce friction, allowing for better expansion or contraction.
