We have added an additional line to the razor marking instructions for the MOUNT on the CXC CLOSSLOC nut, as shown by the red arrow in the picture above.

When the shaft rotates rapidly counterclockwise, CXC CROSSLOC nuts are at increased risk of loosening and pulling the sleeve. For safety, ensure the setscrew is tightened firmly before use. The factory has not tightened it fully to avoid obstructing the shaft during installation.
