Original Gripper® Plugs

Cherne´s Gripper plugs can be used in a variety of applications including DWV (drain, waste and vent) testing and stack testing. End-of-the-pipe design wont fall in, whereas the Inside-of-the-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.
