The RIDGID Tailpiece Extension Cutter is the first cutter of its kind that provides the hassle free ability to execute a clean, fast, and straight cut on thin-walled plastic tube. The New Model P-TEC 2550 can be used on Polyethylene (PE), Polypropylene (PP), and Thin-Walled PVC disposer kits, tailpieces, and wall tubes of two standard sizes: 1-1/4" and 1-1/2" OD; both sizes with the same tool. The Tailpiece Extension Cutter is another addition to the RIDGID Under-the-Sink specialty tools family that have brought tremendous value to service plumbers, plumbing contractors and the DIY.
