Rolling shutters
Sturdy and reliable in tough daily use
Doors close more tightly and have lower wear
The ZAK® System displaces the barrel on the support brackets and precisely guides the door curtain so that it always enters the side guides vertically.
The advantages of the ZAK® system:
- The gap between the rolling door curtain and lintel is closed, sealing the door
- Less abrasion and friction on the rolling door curtain; the door maintains its attractive appearance longer
- Significantly less noise is produced
- Less headroom is required
