Port blocker set Lindy SFP Port Locks Green 10 pcs + 1 key, compatible with SFP, 20×74.5×5.9 mm

The Lindy SFP Port Blocker Key set provides a simple way to secure SFP ports by physically blocking insertion of cables, transceivers or foreign objects. The kit includes ten green moulded plastic blockers and one special insertion/removal key. Each blocker fits and latches into an SFP slot like a connector, remaining semi-permanent until removed with the key. The product suits use in data centres, server rooms, offices and educational or public-sector locations where uncontrolled access to network ports should be limited.

Advantages

The port blockers prevent unauthorised or accidental connection to SFP ports, reduce the risk of physical damage to ports and provide a clear visual indication of inactive or reserved ports. The moulded plastic design latches securely in place and the supplied key enables controlled removal. The compact green blockers are sized to fit standard SFP slots and are delivered as a 10-piece set with one key for convenient deployment.

Suitable for

• Data centres and server rooms
• Managed network racks and switches with SFP slots
• Offices, schools and public-sector network equipment

How to use

To install, fit a blocker onto the insertion key, align it with the SFP port and push until it latches, then withdraw the key while holding the blocker in place. To remove a blocker, insert the key into the blocker until it clicks, then pull the assembly out of the port. The blockers remain semi-permanent and should only be removed with the supplied key.

Usage recommendations

The port blockers act as a basic physical and visual deterrent against tampering and accidental connections; they do not prevent a determined attacker from gaining physical access to an SFP port. Keep the removal key in a controlled location and use the green colour to mark inactive or reserved ports.
