With the Lindy USB Type C / Thunderbolt 3 Port Blocker, you can quickly block open ports and easily prevent users from connecting cables, devices, or inserting foreign objects without permission.

The USB port blocker consists of a combined "key" and "lock" assembly that gets inserted into the USB port. To use it, simply insert the "locking key" into the port and release the latch - the lock stays in place! Insert the key back into the lock to remove it. Easy!

With this small device, system administrators can physically prevent users from connecting Pen Drives, Mobile Phones, and other USB Mass Storage Devices to their computers to copy data and introduce viruses.

Note: these port blockers are only compatible with the corresponding color of the port blocking key.
