Aluminum Counter Roll-Up Doors are specifically manufactured to fit openings that are too small for a regular Aluminum Roll-Up Door, or openings that are designed to be counter. They can also meet a diversity of commercial and institutional application requirements. Doors can be obtained in anodized or powder coated aluminum, and can be motor, chain hoist, crank or manually operated. Some possible applications include, but are not limited to, hospital counters, pass windows at kitchens, cafeterias, post office windows, ticket offices, and check rooms.
