The Protect-O-Gate CLEAR-AISLE model is a revolutionary breakthrough for reducing the potential for falls and other accidents associated with mezzanine loading areas while taking up only 10” of aisle space. When “corral” is raised, ledge gates slide down so the worker has access to the load. Fall potential is eliminated. When “corral” is lowered, ledge gates slide up so the worker is blocked from the staging area.The CLEAR-AISLE provides access to the work area from three sides. It requires only 10” of space on the mezzanine ledge when “corral” is in the raised position. It offers ergonomic, counterbalanced operation. Durable, welded steel construction.
