Security
As manufactured, up and over doors rely on rods actuated by a handle to enter sockets in the frame. This sounds secure enough but in reality it offers a low level of security. We have the video of a break-in that took less than 80 seconds to can open the skin of the door, move the operating rods and gain entry to the building. A bar at the base of the door would have stopped this, but such a bar can be cut off with an angle grinder.
Locking Systems
With our roller shutter door we offer two locking systems. Either or both can be fitted. One is the simple hasp and clip padlocking the base rail to ground which can be employed singly, or in pairs, the other is a plunger that engages with one of the solid slats in the door at mid-height so that locking and unlocking is possible without bending down. Cutting these side locks with an angle grinder is not so easy and very noisy. Even cutting the slats doesn’t work as the linkage continues in the guides which would require a 7′ long vertical cut to remove (difficult).
With our roller shutter door there is no mechanism. The spring and other parts are contained within the roll of slats. And, as an added benefit, there are no levers and springs exposed which could be a safety hazard. Plus all of the interior space is available for storage and shelving.
