Proper and safe functioning of the shutter is possible owing to the safety devices and reinforcements:
Cam lock, installed in the lower or central part of the shell strip and operated from both sides.
Hand-operated bolt – makes it impossible to lift the closed rolling shutter from the outside. Used in the shutters in the aluminium system.
Automatic bolt – installed in the lower strip. It does not require hand operation and efficiently makes it impossible to lift the shutter from the outside.
Lower strip reinforcement - stabilizes the shell operation and makes it impossible to pull out the shell from the guides. It is recommended for the rolling shutters with the increased resistance to burglary.
Guide masking frame (in aluminium rolling shutters) – makes it impossible to unscrew the guide.
Guide with extended leading chamber (in aluminium rolling shutters) - stabilizes the shell operation and makes it impossible to pull out the shell from the guides.
Casing with the increased resistance to burglary - made of aluminium profiles filled with hardened polyurethane foam, which increases the rolling shutter strength.
Blocking suspension rod (in the shutters with electric drive and chain gear) -installed on the shutter shaft. It blocks the shell of the closed shutter, making it impossible to lift it from the outside.
Hook protection (in the aluminium shutter box) – makes it impossible to lift the shutter from the outside.
Integration with the alarm system – each unwanted attempt at lifting the rolling shutter initiates the alarm signalling.
