I am aware that this is a custom made coax cable and Non-returnable, 3-5 days for assembly.

CNT-400-P Coaxial Plenum cable is an indoor, fire retardant cable specifically designed for use in return air handling plenums. Low loss, braided coaxial cable offers similar performance compared to corrugated copper products but with higher flexibility. Designed to be used in applications where handling characteristics, improved shielding and low loss is required.

Because these cables are custom made to order, they are not returnable. Please double check your order for accuracy!
