3/8 Inch Slit Red Wire loom Tubing. Our 3/8 red wire loom is an automotive grade wire covering and is corrugated for flexibility and strength. The wire loom is slit to allow for easy wire insertion. Great for protecting wires from abrasion and other damage. Made from red polypropylene. Can be secured with red cable ties or with 1/2 inch cable clamps. *NOTE: Our red cable ties are from a different manufacturer and are a slightly different shade of red from the red wire loom.
