ABSTRACT:
An apparatus for use in marking a length of cylindrical pipe to permit the pipe to be cut for use in an assembly and arranged so that a plurality of markings on a length of pipe can be accurately oriented relative to each other. The device has a tubular plastic sleeve that is split in a plane of the sleeve longitudinal axis, the sleeve being flexible so as to permit the sleeve to be expanded over and subsequently to conform to the external surface of a pipe. The sleeve has at least one end with a configuration of a desired marking. A bubble level is affixed to the exterior surface of the sleeve so that when the sleeve is used to make more than one marking on a length of pipe, the markings can be axially oriented with respect to each other.
