RJ45 Socket Lock Alantec WT-BG-06, yellow — physical RJ45 port blocker

Alantec WT-BG-06 is a physical RJ45 socket lock in yellow designed to prevent unauthorized insertion of Ethernet plugs into standard RJ45 female ports. The device mechanically blocks access to the jack, reducing the risk of unauthorized network connections and accidental data leaks. It is compatible with typical desktop, laptop and network equipment ports and is intended for environments where simple, visible port control is required.

Advantages

The Alantec WT-BG-06 provides a straightforward mechanical barrier that does not require software, power or configuration. Its bright yellow color makes blocked ports easy to identify during routine inspections. The lock is lightweight, easy to install and remove when authorized access is needed, and is suitable for repeated use without altering the port or nearby cabling. It offers a low-cost, non-invasive method to limit physical access to Ethernet ports.

Suitable for

• Server rooms and data centers to restrict unused ports
• Office workstations and hot-desking areas
• Public terminals, kiosks and shared computers
• Network cabinets and patch panels in managed environments

Key specifications

• Form factor: mechanical RJ45 port blocker designed for standard female RJ45 sockets
• Color: yellow for high visibility
• Material: durable plastic construction for repeated insertion and removal
• Compatibility: fits standard 8P8C (RJ45) female Ethernet ports on equipment and patch panels
• Operation: passive, no power or software required

How to use

Insert the Alantec WT-BG-06 directly into an empty RJ45 female port until it sits securely and blocks access to the contact area. To allow an authorized connection, remove the blocker by pulling it straight out from the port. No tools, software or configuration changes are needed. For best results, install the blocker in ports that are not in active use and label or document blocked ports according to your site control procedures.

Usage recommendations

Use the RJ45 socket lock as part of a broader physical security practice: combine it with administrative controls, port labeling, and regular inspections. Avoid forcing the blocker into damaged or non-standard ports to prevent equipment harm. Keep a controlled inventory of blockers and train staff on authorized removal procedures to maintain network integrity.
