Camstopper Retrieval

ASP CAMSTOPPER® is the world's fastest and safest mechanical pipeline plug to install and retrieve

ASP CAMSTOPPER® is designed specially for drain and sewer applications (typical operating pressure from 0.3 up to 0.5 bar).

  • Safest stopper ever designed
  • Non man-entry retrieval
  • 20 times quicker to install and retrieve
  • Longer lasting durable seal
  • Quality EPDM
  • Allows improved compliance with Confined Spaces Regulations 1997
