This is a simple USB port lock. It will keep people from removing a usb plug from its charger/port.

To install follow the pictures above. First insert the lock into and empty USB slot with the two teeth facing down. These two teeth lock into the bottom of the USB port. Then install your USB plug into the port. Next attach a zip tie between the groves on the back of the lock. Be sure to install it in a place where the cord will not be able to wiggle in or out. Usually there is a extra jacket you can zip right behind.

When in place a user will not be able to pull the USB port out without cutting the zip tie. This won't stop a determined thief but it is more than enough to deter your average user/patron/family member from messing about with things they shouldn't.

Make sure you use your slicers bridge settings for best results.

The original lock works great for USB plugs and most things but some desktops have an extra mm or so between the plug and the socket so use the "long" version if the regular ones teeth can't quite reach the sockets indents.
