Ster knop, veiligheid, afsluitbaar

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.
