Lindy Rj-45 Port Blocker Key Black

Physical Security, Locked In

Block Unused Network Ports to Prevent Unauthorised Access

The Lindy RJ45 Port Blocker provides a simple, effective way to physically secure unused Ethernet ports across IT and AV networks. Ideal for switches, patch panels, wall sockets, and exposed endpoints, these blockers help prevent the unauthorised connection of network cables, rogue devices, or foreign objects.

Whether used to enforce network security, indicate inactive ports, or protect against accidental damage, the Lindy RJ45 Port Blocker is a fast, scalable solution for IT administrators, AV integrators, and facilities managers. Each blocker uses a secure latching mechanism — similar to a standard RJ45 plug — and can only be removed using a matching colour-coded key.

Black, Green, Orange and Yellow versions for differentiated access control. Additional keys and blocker packs also available.

Note: Keys are colour-specific and only compatible with blockers of the same colour.
