Reed offers the best designed tools for stopping flow in PE pipe, with capacities ranging from 1/2in to 8in. The PES1 series features a stationary bottom bar while the PES4 and PES2 series utilize an affixed bottom bar that swings open to fit over any location on the pipe. Additional features include aluminum parts for lighter weight, sliding bar handles for working in tight places, fine-pitched thread for a controlled, low effort squeeze, and grease fittings for easy operation and long life. All tools use positive stops to prevent damage caused by over-clamping.
