Application examples
Back checks are used, for instance, in situations where doors and windows can hit a wall or similar in an uncontrolled manner or be torn out of the user’s hand by wind, draft or even during normal opening. They ensure that hinged doors and windows do not slam open without control. They dampen excessive opening speed and limit the opening angle. This protects the door/window and the hardware. Thanks to a large number of installation accessories, many installation options are possible for almost any application.
