Siral Roller shutter lock

This Roller shutter locking device significantly increases the security of your home without having to make a hole in the guide or roller shutter armour. This locking device is an ideal solution.
By simply clamping this clamp between the roller shutter and the guide rail, pushing up the roller shutter armour is prevented in the event of a burglary, as the small teeth of the locking device bite down. The latch works even when the Roller shutter is slightly open.
This Roller shutter lock will, however, leave small scratches on the inside of the guide and armour.
