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.

Original Gripper® Plug Features:
• Ideal for sewer testing and long-term applications
• Made with glass-reinforced ABS plastic
• End-of-pipe design seals only at the end of a pipe
• Inside-of-pipe design seals inside pipe as far as needed

Equipped with:
• Easy to install extra large zinc wing nut – won't rust
• Natural rubber o-ring
• Galvanized carriage bolt to prevent corrosion
