The Gliderol High Security Roller Shutters comes with a patented self-locking design that can resist substantial upward lifting force without the need for a physical lock, making it suitable for security applications in industrial and commercial buildings.
Through our unique patented* design, the door automatically locks when fully closed, without the need for a physical lockset. Any attempt to lift the door will cause the door curtain to wedge at the guides. The greater the upward lifting force applied, the tighter the wedge. Hence, it is practically impossible to lift up the shutter by force, making this product ideal for protecting glass showcases of high value merchandise and cash-dispensing counters.
