PEX-a Pipe Support is a non-combustible, self-gripping, galvanized-steel channel for cross linked polyethylene (PEX-a) pipe. It provides continuous, uninterrupted support of PEX-a pipe, allowing hanger placement similar to that of metallic pipe. Use PEX-a Pipe Support in conjunction with un-insulated Uponor AquaPEX or Wirsbo hePEX PEX-a pipe in ASTM E84 plenum applications. The PEX-a pipe with pipe support can be insulated with typical CTS (copper tube size) pipe insulation. PEX-a Pipe Support is offered in 9-foot lengths
