The TrapMaster from CPI Products allows for most standard push camera systems to negotiate bends and corners and 180-degree P-traps in 4- to 6-inch pipes while centering the camera at all times. Eight wheels are mounted on two separate skids spaced roughly 2 inches apart. The front section mounts to the camera head while the rear mounts at the optimal spot along the camera head or spring push cable. Each section of the skid has four rocking SeamLeapers that swivel back and forth and adjust to various radiuses in the pipe, providing better wheel contact and maneuverability. 413/443-0925; www.cplasproducts.com.
