Why Dynamic ClosuresInnovation is our cornerstone

The best security grille or door for a store, office, or kiosk needs to be a fortress, but doesn’t need to look like one. The right design can showcase products to window shoppers, harmonize with site architecture, and even add prestige to your client’s brand.

Founded in 1975 on the invention of the side folding security grille, we continue to advance our designs every year for better usability, durability, security, and aesthetics. From our manufacturing facility on the St. Lawrence River, our products serve three continents.
