* The Accordion Shutter is an economical alternative to a roll shutter, a very strong and durable shutter that moves horizontally between an upper and lower track.

* It requires stack space on either or both sides. Interlocking aluminum blades make up the protective wall of the shutter.

* The accordion shutter glides along on tracks and a wheel assembly attached at the top provides easy free gliding movements. The accordion shutter can open and close as one unit, move from left to right or right to left.
