Port blocker Smartkeeper MNL04PKGY RJ-11 Grey Plastic

The Smartkeeper MNL04PKGY is a compact port blocker designed for RJ-11 (telephone) connectors. Made from durable grey plastic, this port blocker physically prevents unauthorized use of telephone lines and protects LAN-adjacent ports in environments with limited space for maneuver. The product includes a thin, high-strength Mini Port Lock key that fits the plug-in head and is protected against mechanical damage to ensure reliable locking and unlocking.

Advantages

The device provides a purely mechanical security solution that requires no power or software, reducing complexity and maintenance. Its slim design and hardened key material offer maximum security for small ports while remaining comfortable to handle. The plug-in key head is shielded from unwanted mechanical influence, and the overall construction is suited for narrow or crowded computer environments.

Suitable for

• Securing RJ-11 telephone ports in offices and public areas
• Preventing unauthorized access via telephone/LAN-adjacent ports
• Use in environments with limited space around connectors (racks, kiosks, compact workstations)
