It allows the driver to manage product flow across five separate compartments without climbing onto the trailer, which improves safety and speeds up unloading. These units experience wear at the linkage and pivot points over time, necessitating replacement when operation becomes stiff, sloppy, or a compartment fails to open or close fully. Based on available listings, this part is associated with cable-operated systems and is often paired with air valves on gas or liquid tank trailers.
