Model 681

For applications when security is a priority, but you want to maximize air circulation, light infiltration and visual access to interior spaces. Short on the space required for installation, but long on handsome good looks, these grilles secure premises and guard against theft and debris with superior compactness and nearly endless design possibilities.

Open-air side-folding grilles provide security, while allowing air circulation and full visual access to interior spaces. This security grille offers a wide range of features to fit most any application where an open-air grille satisfies security requirements, such as in retail environments, malls, schools, offices and airports.
