MP0042 RJ45 port blocker (1x key, 10x locks)

This product helps to protect against un-authorized access to a network or system, as well as preventing unintentional or malicious damage to ports. It can also act as a visual cue, showing inactive or disconnected ports. It can quickly block open network ports and prevent users from connecting cables, devices or inserting foreign objects without permission. The lock secures itself to the RJ45 port and can be removed with the attached key again.
