This is a device with two spring arches, which is triggered automatically when the door is pulled to the closed position. They automatically act as stops and are secured against forcing in the opposite direction. These systems have been tested in combination with various door systems of RC 2 and RC 3 security doors with hooks.

For increased 5-point safety stresses up to resistance class 3 (RC3: Intrusion Test with two screwdrivers and wrenches) at wide profiles, the door may be provided above or below the primary lock with various additional locks such as these beak closures.
