Order No. 3.27.x
By using the elastic opening delimited (backcheck function), the door is slowed down at the desired opening angle. Any unintentional pushing when opening the door, e.g. of adjoining walls or other objects, can thus be avoided.
- Subsequent installation is possible at any time.
- Setting range from 80° to 120°.
- Elasticity range max. 20°.
- Also usable in combination with the locking device.
The elastic opening delimited (backcheck function) is not an overload protection and does not replace the door closer in many applications.
