Based on user response to the Universal Roller Skid (URS1) for 6”-12” pipelines and the demand that followed, CPI Products has developed the Mini URS (URS4) for 4”-6” pipelines. The Mini keeps your camera centered in the pipeline and protects it from wear and tear. Eight wheels mounted on the skid allow the camera to roll easily in 4” and 6” pipelines. The Mini easily negotiates 90° bends. The Mini URS is constructed of the same lightweight, durable, corrosion resistant composite nylon as the larger version. This product does not include a push camera.
