The Wohler USA 4705 VIS Camera Trolley offers optimal guidance of the camera head in ventilation ducts, water pipes, and flue gas lines up to 6 inches in size. The combination with the optional light ring (not included) and stabilization sleeve (not included) creates an even better illumination and increases handling within the pipe or duct.

The best possible view in the pipe is offered due to the numerous adjustment options. The camera head can be securely attached onto the trolley or hung below the trolley for additional protection. This positioning offers the best clearance between the optics and the pipe walls. Regardless of how the camera head is attached to the trolley, users can keep control and receive the best possible insight.
