Coil machines and lockers are the bread and butter of Industrial Vending. AIS Keepers are built with state-of-the-art materials and technology. They are purposely designed to be rugged, reliable, and reasonably priced. The Keeper Care System® permits mobility of each Keeper so work supplies and tools are located where they are used. All Glass-front Keepers feature the patented Sensit® Guaranteed Delivery System. At our manufacturing plant in Kearneysville, West Virginia, each Keeper is inspected and signed for before it leaves our plant.
