Port blocker Lindy RJ45 Port Locks Yellow 10x + 1 Key

The Lindy RJ-45 Port Blocker Key set (yellow) includes ten semi-permanent RJ-45 blocking caps and one insertion/removal key. Each plastic blocker plugs into a network RJ-45 port and latches in place like a standard cable connector, providing a simple physical and visual barrier to prevent unauthorized cable connections, accidental insertion of objects or unintentional port damage. Dimensions: 20 mm width, 74.5 mm depth, 5.9 mm height.

Advantages

The kit offers a fast, tool-free method to secure open RJ-45 ports using a molded plastic cap and a dedicated key for insertion and removal. Blockers remain seated until removed with the key, serve as a visible indicator of inactive ports and are suitable for environments where basic physical deterrence and port protection are required. The product is compact, lightweight and available in yellow for easy identification.

Suitable for

• Schools and educational facilities
• Offices and open-plan workspaces
• Public sector and shared network areas
• Server rooms for temporary port blocking
• Preventing accidental or casual access to network ports

How to use

Attach a blocker to the insertion key, align it with the RJ-45 port and push in until the blocker latches in place. Release the key by holding the blocker and pulling the key away.

Usage recommendations

Use the port blockers as a basic physical and visual deterrent only. They do not replace network access control or lockable network cabinets and will not prevent a determined attacker from gaining physical access to RJ-45 ports. Keep the key secured and match key colour to blocker colour when replacing or expanding the set.
