One one type boots null for universal joint

摘要

A split boot formed from a unitary, flexible body shaped to be helically wrapped around a universal joint or the like. Once the flexible body is wrapped around the joint with the mating edges engaged a main body is formed having a generally hollow truncated conical configuration with a corrugated or helical shape. One end of the main body has a smaller circular cross section than the other end. Each end portion of the main body has cutting guide ridges such that the diameter of the aperture in the end may be varied by removing some of the material from the body.
