## Long description

The Lindy RJ‑45 port blocker key (model 47899) is a yellow security key designed for use with Lindy RJ‑45 port blocker covers. Measuring 20 × 74.5 × 5.9 mm, the key is used to insert and remove semi‑permanent plastic blocking caps that latch into RJ‑45 ports, preventing unauthorized cable connection, tampering or accidental damage. The key is compatible with the matching colour series of Lindy port blockers and is intended for environments where physical control of network ports is required, such as offices, server rooms and public access areas.
Advantages
The port blocker key enables fast, repeatable locking and removal of blocking caps without tools. It provides a clear visual indication of inactive or secured ports and reduces the risk of unauthorized or accidental connections. Made from durable ABS plastic, the key is lightweight yet robust for regular use. As a purpose‑designed accessory for Lindy RJ‑45 port blocker systems, it ensures correct engagement and easy operation when used with compatible blockers.
Suitable for
 Securing RJ‑45 ports in offices and meeting rooms
 Protecting network ports in server rooms and data closets
 Controlling access to network sockets in schools and public facilities
 Visual identification of inactive or reserved ports
Key specifications
 Colour: Yellow
 Dimensions: 20 × 74.5 × 5.9 mm
 Material: Acrylonitrile butadiene styrene (ABS)
 Designed for use with Lindy RJ‑45 port blocker covers (matching colour)
 Single‑port insertion/removal key
How to use
Attach a compatible Lindy port blocker cap to the key and insert the blocker into the RJ‑45 port until it seats like a standard connector. Hold the blocker in place and withdraw the key to leave the cap latched in the port. To remove the blocker, reinsert the key fully into the blocker until it clicks, then pull the blocker and key out together. Use only with matching Lindy port blocker caps; do not force the key into incompatible products.
Usage recommendations
Use the key only with Lindy port blocker covers of the corresponding colour and generation. Port blockers act as a basic physical and visual deterrent but do not provide absolute protection against determined attempts to access a port. Inspect blockers and the key periodically for wear or damage and replace if deformation or cracking is visible. Keep spare blockers and keys stored securely to maintain controlled access management.
