Rolling grilles are ideal deterrents to smash-and-grab, break-ins, and vandalism. They are used extensively in such diverse locations as big box stores, plaza storefronts, and mall store entrances. Rolling products can be mounted on self-supporting steel tubes secured to the ceiling joists and the concrete slab, allowing the installation to be the first item completed on the project. Clear anodized finish on the entire aluminum curtain and bottom bar is standard. Curtains should stay pleasing to the eye long after the bill is paid. Many custom finishes are available. Operation is by choice of electric motor, hand crank, chain hoist, or push-up.
