Patent attributes
A piping alignment tool suitable for locating where an extension of an existing pipe must pass through obstructions such as walls. The tool has a tubular shape with oppositely disposed ends. Each end is formed to have multiple coaxial sets of different-sized pipe threads that allow the tool to be threaded onto a pipe having one of the pipe thread sizes formed on the tool. The tool is also equipped to generate light beams from each end, so that the light beam can be emitted from an end of the tool opposite a pipe onto which the tool has been threaded. By threading the tool onto a pipe and emitting a light beam from the end of the tool opposite the pipe, the location of an obstruction beyond the existing pipe is illuminated by the emitted light beam.
