NOTE: This is soft, high-gloss PVC sleeving that is identical in color, surface finish, inner diameter, and wall thickness to the vinyl sleeving that was used originally by the factory. It is NOT heat shrink tubing. All sizes of our sleeving are sold in continuous lengths, up to a maximum continuous length of 20 feet. If you enter a quantity of "6" (feet) in the shopping cart, you get six continuous feet, not six pieces that are each one-foot long. If you enter "40" (feet), you get two 20-foot lengths.Continuous lengths of greater than 20 feet are simply too unwieldy for packing/shipping purposes.
