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
