They are well suited to large storefront openings as they roll up and out of the way when opened. Grilles effectively secure an opening to deter unlawful entry while maintaining good visibility through the grilles to the retail displays and signage in the store. In shopping malls and other indoor applications, grilles can serve as the primary method of securing the business or your pharmacy area. For exterior storefronts, grilles compliment your existing door and window systems and reduce the risk of smash-and-grab theft. Security grilles are available in an array of grille styles and colors. Grille options also include manually deployed or powered grilles.
