Our Accordion Shutters combine strength, ease of operation and economy into a shutter system that neatly stacks to either side of the window or door. Ideal for enclosing balconies, the Accordion Shutters storage stack is approximately one inch per linear foot of coverage. The positive keyed locking system offers protection against hurricane force winds, flying debris, rain and forced entry. Extruded aluminum and stainless steel construction provide lasting service, even under severe coastal conditions.
