Problem solutions for malfunctioning doors
Make sure the correct cable drums are mounted.
Check if the cable tension in a closed door on the left and right are equal.
High lift system, Does the cable run on the flat part of the cable drum as soon as the first roller passes the curve?
Are the right springs mounted?
Check the spring diameter
Check the wire diameter (measure the length of 10 turns and divide by 10)
Check the spring length
The rollers must be adjusted to minimize the friction between the door panels and the vertical weather strip. You should be able to turn the rollers by hand when the door is in the closed position.
Do the track run parallel in the vertical and horizontal planes.
Are there any obstructions during opening/closing, check the tolerances between the door panel and track.

It is possible to use this system with 0mm mounting space.
Are panels available in different RAL colors?

Do you have products that reduce the sound production of a sectional door?
By applying Silent roller (25239) the noise will be reduced.
For industrial doors you can use spring filler 30002 with the end plugs 30003 to reduce the noise of the springs.
What is the advantage of shot blasted springs over black / galvanized springs?
Shot blasted springs have a service life of 25.000 cycles due to their special treatment. They are silver coated to emphasize their quality. As the springs have a higher capacity, the weight can be kept lower – specifically for industrial doors. Because of the weight reduction, you will often pay less for a higher quality and better looking spring!!
