Replacement Locking Clips

Lock Ethernet cords in place to prevent unauthorized removal from ports. These security clips slide over RJ45 connectors, and can only be taken off with the included security keys. They can also be used with an RJ45 plug as a port blocker—no Ethernet cord required—to keep out heavy dust and unwanted connections.
