The Jackson Safety Pipe Flange Aligner (#10) is a self-determining flange aligning tool that allows quick and accurate measuring.  The aligner inserts easily into the pipe, centers snugly against the pipe’s inside diameter, and automatically aligns with the pipe access.  It’s a manual tool that takes the guess work out of pipe construction.
