Rolling Grilles


Are grilles with glazed G.E. Lexan® (or equal) panels in the curtain design.The panel modules are clear 12″ x 3″, 1/8″ thick flame-retardant polycarbonate material that provides additional protection from theft of small articles through the curtain and creates a barrier against refuse, odors, and smoke. The panels are secured by bronze color molded nylon links that are attached to 5/16″ diameter solid aluminum horizontal rods of alloy 5056 H32.


Are open design grilles allowing free circulation of air and full visual access to the area being protected. The curtain is comprised of a series of 5/16″ diameter solid aluminum (stainless or galvanized optional) rods of alloy 5056 H32 at 2″ on center (1 1/2″ optional). Supporting the horizontal rods are vertical chains formed of eyeletted aluminum (stainless optional) spaced at 9″ apart. For added security, the chains may be specified to be spaced at 6″ or 3″ apart.
