SECUIRTY SHUTTER
Self-locking Aluminium Roller Shutters for high security applications
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. Very effective against looting and all forms of forced entry.
