Gripper

The Cherne® Gripper® Plugs can be used in a variety of applications including DWV (Drain, Waste and Vent) Testing and Stack Testing. End-of-Pipe design won’t fall in, whereas the Inside-of-Pipe design allows you to locate the plug inside the pipe as far as you need. Time tested, the Gripper remains one of the most popular mechanical plugs on the market.
