Port blocker Lindy RJ-45 Port Blockers Without Key Pack of 20 Yellow

The Lindy RJ-45 Port Blocker pack contains 20 yellow semi-permanent blockers designed to prevent unauthorised connections to RJ-45 network ports. Each blocker is a moulded ABS plastic cap that latches into an RJ-45 socket like a network plug and stays in place until removed with the supplied insertion key. The bright yellow colour provides a clear visual indication of inactive or secured ports and is suitable for schools, offices and other public environments where controlled network access is required.

Advantages

These RJ-45 port blockers provide a simple physical and visual deterrent against unapproved cable connections and insertion of foreign objects. Made from durable ABS plastic, each blocker fits securely into standard RJ-45 sockets and is removed only with the matching insertion key, helping to reduce accidental or casual tampering while remaining easy to install and remove by authorised personnel.

Suitable for (tasks / use cases)

• Securing inactive or spare RJ-45 ports in offices

• Marking disconnected or reserved ports for network management

How to use

Attach a port blocker to the insertion key and push the blocker firmly into the RJ-45 port until it latches in place. Hold the blocker steady and withdraw the key, leaving the blocker installed. To remove a blocker, insert the key back into the blocker until it clicks, then pull the key and blocker out together. The blocker remains semi-permanent in the port and requires the key for removal.

Recommendations

Use these blockers as a basic physical and visual deterrent; they do not provide strong physical security and will not stop a determined attacker with tools. Keep the insertion key secure and use matching-colour keys where applicable. Verify compatibility with your RJ-45 jack type before deployment.
