Use this RJ45 port lock to secure RJ45 sockets against unwanted insertion of connection cables. This also prevents unauthorized access via the network. The lock secures itself in the RJ45 port and can be removed with the included key. It flushes with the front of the RJ45 port within the housing, making it difficult to pull out easily. For safety reasons, please note that this lock can also be disassembled with skill and appropriate tools. Please be aware that the key only fits the lock of the same color.
