The rotary clamping latches GN 516 have a closing mechanism which transfers the rotary movement of the operating element (key) into a 90° turn and then into a 6 mm linear stroke.

This mechanism is designed for common applications such as making a tight and vibration-proof interlock in the end position (retaining position)in connection with an elastic element, such as a door or casing seal.

Latch arms with different bend angles cover a latch arm distance A (retaining range) from 17 to 63 mm. If the measured retaining position lies between two latch arm distances A, the next smaller value must be selected.

The rotary clamping latches GN 516 are are supplied with loosely enclosed latch arm.
