Port blocker Lindy RJ-45 (pack of 20) – black, ABS, 20×74.5×5.9 mm

The Lindy RJ-45 Port Blocker Key pack contains twenty injection-moulded ABS blockers designed to obstruct RJ-45 network ports and prevent unauthorised cable connections. Each black blocker measures 20 × 74.5 × 5.9 mm and fits the port similarly to a standard network plug, remaining in place until removed with the matching insertion key. These semi-permanent blockers are suitable for controlling network access and reducing accidental or unwanted use of ports in offices, classrooms and other public environments.

Advantages

These port blockers provide a simple physical and visual deterrent against unauthorised connections and accidental port use. Made from durable ABS plastic, each blocker latches into an RJ-45 socket using the supplied insertion key and stays securely in place until the key is used to remove it. Supplied as a pack of 20 in black, they are suitable for deploying across multiple devices or locations.

Suitable for

• Preventing unauthorised cable connections in offices
• Securing network ports in schools and classrooms

How to use

Attach a blocker to the insertion key, align it with the RJ-45 socket and push the blocker into the port until it latches, then release and withdraw the key. To remove a blocker, insert the key into the blocker until it clicks into place and then pull the blocker out. The blocker fits and latches like a normal network plug and requires the matching key for removal.

Recommendations

These port blockers provide only a basic physical and visual deterrent; they reduce accidental or casual access but will not stop a determined individual from gaining physical access to an RJ-45 port. Keep the insertion key secure and use matching-colour blockers if colour-coded identification is required.
