USB Type C port blockers are useful devices that can be used by system administrators to physically prevent access to USB ports.

USB blockers allow the placement and removal of locks from USB ports, preventing unauthorized users from inserting memory sticks, mass storage devices, and mobile devices into shared workstations or devices with USB ports in public spaces.

The usage process is simple: just place a key in the lock and insert it into the USB port. Release the mechanism on the key to leave the lock in place. To remove it, simply insert the key back into the lock and pull it away.
