The Automatic Fastener is a right-angled, slidable, power-locking connection with a high load-bearing capacity. The main advantage when installing this fastener is that no profile machining is required. The fastener is screwed directly into the end face of an aluminium profile, thus creating, a secure connection in a matter of seconds. As a result, the Automatic Fastener can be easily fitted to existing aluminium profile structures. item Automatic-Fastening Sets are available for Lines 5, 6, 8 and 12. Automatic-Fastening Sets should be used in pairs.
