threaded knob / star / steel / polyamide
Safety star knobs GN 5337.9 are designed to prevent unauthorised use.
To engage and release, the key must be inserted and turned by 180°, creating a formlock between the handle and the threaded bushing or screw. Turning the key back by 180° will release the connection.
The key can be inserted and pulled off in both end positions.
Two keys per star knob are included with the delivery.
