## Summary description

The Lindy RJ-45 Port Blocker key is designed to secure RJ-45 ports. It features a black color and dimensions of 20mm width, 74.5mm depth, and 5.9mm height. This product helps prevent unauthorized access to network ports, ensuring network security and integrity.

## Long description

The Lindy RJ-45 Port Blocker Key is a locking insertion tool designed to work with Lindy semi-permanent RJ-45 port blockers. It allows administrators to quickly block unused Ethernet ports to prevent cable insertion, unauthorised device connection or the introduction of foreign objects. The key is made to match the corresponding colour of Lindy port blockers and is compatible only with the same-generation blockers. Dimensions: 20 mm width, 74.5 mm depth, 5.9 mm height; colour: black.
Advantages
The port blocker key provides a simple physical and visual deterrent against casual tampering and accidental connections. It enables secure insertion and removal of the moulded blocking cap, ensuring the blocker latches into the RJ-45 port like a network plug and remains semi-permanently in place until intentionally removed. The compact plastic design is appropriate for environments such as schools, offices and other public sector locations where visible port control is required.
Suitable for (tasks / use cases)
Preventing unauthorised connection of network cables
Protecting RJ-45 ports from foreign objects and accidental damage
Marking inactive or disconnected ports in offices, schools and public buildings
Managing port access in shared or multi-user network environments

Model / MPN: 47890
EAN: 4002888478908
Colour: Black
Dimensions: 20 mm (width) × 74.5 mm (depth) × 5.9 mm (height)
Compatibility: Works with same-generation Lindy RJ-45 semi-permanent port blockers of matching colour
How to use
Attach the port blocker to the insertion key and push it into the RJ-45 port until the blocker latches in place as a network plug would. Hold the blocker in position and withdraw the key; the blocker will remain in the port. To remove the blocker, reinsert the key into the blocker until it clicks, then pull the key and blocker out together. Follow these steps for each port you intend to block or unblock.
Usage recommendations
These port blockers provide a basic physical and visual deterrent against tampering and accidental connection. They are not a replacement for physical security measures and will not stop a determined individual from gaining access to a port. Use the correct colour-coded key with matching Lindy blockers and verify compatibility with your existing port-blocker generation before purchase.
