For users of a hand- or arm orthosis (supporting device), a special version of the system was devoloped: Free Lock Orthosis Grip (FL-OG). This device is shaped in such a way, that the system can be fitted underneath the socket of a hand- or arm orthosis.

 

With this Free Lock OG, people who suffer from a brachial plexus injury (BPI) can also make use of the Free Lock-system.

 

Free Lock OG does not have a wrist unit of it's own and therefore has to be attached to the socket of the orthosis at just the right distance, height and angle to the handlebar.
