The mechanical quick-release fastener can be used to quickly and effortlessly clamp and release various Quick•Point® products. For example, the quick-release fastener can be mounted on a Quick•Point® plate in just a few seconds. Instead of the usual clamping mechanism with a tightening screw, the clamping device is clamped by means of a 180° closing movement with the clamping lever of the quick-release fastener.
