Open-Air Side-Folding Security Grilles
Open-air side-folding grilles provide security while allowing airflow and full visual access to interior spaces. The 681/682/683/684 Series offer versatile solutions for applications where open visibility and protection are both required, such as retail stores, malls, schools, offices, and airports.
This product line features a variety of curtain patterns, colors, and finishes. Several models are available with wide-body panels, and the 681-E and 683-E Series include an economical high-impact extruded polymer (HIEP) curtain. A countertop version is also available.
