The RIDGID 47793 36 mm Pipe Guide is suitable for use with the SeeSnake microReel, MAX rM200 Series, and Compact2 camera systems. The pipe guide fits a 25 mm camera head. It is designed to help center the camera in pipes, keeping the camera clear of bottom sludge in the pipe. By bringing the camera head closer to the center of the pipe, the pipe guide improves picture quality, allowing the camera to see equally in all directions and helping to keep the camera lens clear during inspections.
