This little clip is done in the Klick Fast style and is used for connecting your Recall Focus and Recall Vision Camera to a Klick Fast Dock.
When combined with an Official Peter Jones Klick Fast docking point, it creates a very secure attachment which can be rotated almost 360° to different points.
The clip is very solidly built from a combination of metal and plastic. Once locked in place, can only be removed from the camera by lifting the integrated metal locking flap.
The simple slim design means your body camera is not protruding too far away from your body, so decreases the chance of it being caught up if involved in any altercations or scuffles.
