Universal Roller Skids from CPI Products protect push cameras and enable them to go farther down the pipe and return with less strain on the cable. They provide a durable plastic enclosure around the camera body, with wheels to move smoothly down the pipe, around corners and over seams. They have movable arms that expand and contract to center the camera and jump over debris, seams and move around corners. A light kit is available to improve the camera image, and a large wheel kit enables it to be centered in pipes up to 16 inches in diameter. The TrapMaster is designed to enable cameras to navigate traps and seams in pipes 4 to 6 inches in diameter. The PoleCat converts a push camera to a pole camera to enable easy control of the camera. 413-443-0925; www.cplasproducts.com.
