I thought this was a wrench for dealing with 1 1/4-1 1/2 PVC sink, bath, and lav problems. Not the case. This instrument is designed for something entirely different. The jaws will not close on 1 1/4" nuts and will barely close on 1 1/2" nuts. There is no way that this is a plumbing tool for lav and sink drains. Perhaps it will work on tightening sink strainers, but I have other tools for that. Do not buy this for work on 1 1/4 to 1 1/2 PVC.
