The Trapmaster from CPI Products, a division of Cavallero Plastics, enables inspection cameras to negotiate through 180-degree P-traps. The design consists of eight wheels mounted on two skids spaced roughly 2 inches apart. The front section mounts to the camera head while the rear section 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, allowing for wheel contact and maneuverability. It allows for most standard push camera systems to negotiate traps, bends and corners in 4- to 6-inch pipelines while centering the camera at all times. 413/443-0925; www.cplasproducts.com.
