Abstract
A pipe protector is disclosed comprising a tubular rubber member with an inner diameter sized to the approximate outer diameter of a pipe. The protector is a variable diameter pipe protector that prevents slipping on undersized pipes, but can also be used on full sized pipes. The pipe protector is capable of surrounding a full size outer diameter pipe and is provided with at least one rubber flap attached to the inside surface to compensate for undersize pipe diameters.
