Cherne’s 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.
