Roller shutter box - The burglar-resistant, extruded covers of the heroal roller shutter box made of a high-quality aluminium alloy are available in resistance classes RC 2 and RC 3. This is ensured by wall thicknesses of more than 3 mm, a safety lock that can only be opened with a special key, and box caps made of resistant steel.
Anti-lift device - It is often easy for burglars to break into your house by simply pushing up the roller shutters. A double anti-lift device prevents burglars from using physical force to push the roller shutter upwards. The first part of the device is a link anti-lift mechanism in the box, which wedges itself and pushes the shutters down. The second is a tilt latch in the area of the end slat. When closed, this latch folds out and prevents the shutters from being pushed up.
Aluminium - Aluminium or stainless steel - All components of the security shutters are made of aluminium or stainless steel with extra thick walls. This makes your security shutters particularly stable and durable. For customers with increased security needs, heroal security shutters are also available in stainless steel for additional burglary protection.
Guide rail - All heroal roller shutters have an extremely strong extruded guide rail and contain a crosspiece for safety locking. This makes it difficult to push up or pry open the roller shutter curtain.
Tilt latch end slat - Due to the three-part, tilt latch end slat, it is not possible to pry open, push up or rip out the shutters.
