How to use:

Rotate the cover counterclockwise to open; rotate clockwise to close. Ensure the cover is closed securely to prevent it from unscrewing; however, do not overtighten, as this may strip the hardware.

Environmental factors such as humidity, temperature and vibrations can cause hardware to loosen, so be sure to routinely verify its security after moving it between different settings.
