PortPlugs USB-A Port Blocker (5-Pack) with Key — High-Security Metal Locks for Desktops, Laptops, Servers

Control USB access with a tangible, easy-to-use solution

PortPlugs USB-A Port Blocker (5-pack) with a matching metal key gives you physical control over USB-A ports on desktops, laptops, servers, docking stations, printers, routers, and more. Built to deter unauthorized access, it helps reduce the risk of thumb drives being connected and unapproved charging in shared or public environments. This is not software; it is a hardware layer of security that complements existing IT protocols.

Rotating-key protection you can rely on

The unique rotating-key mechanism has been a staple in IT environments for years. To engage the lock, insert the blocker into a USB-A port and twist the metal key a quarter turn, then pull the key free. Unlock by reversing the motion. The motion is precise, tactile, and designed for quick deployment when needed.

• Five blockers plus one matching key means you can cover multiple ports across devices or spaces
• Quarter-turn locking provides physical access control without software configuration
• Durable metal construction sits flush in ports and releases cleanly with the included key
• RoHS compliant for long-term use with desktop, laptop, and port-equipped devices

Broad compatibility and real-world use

These blockers fit USB-A 2.0, 3.0, 3.1, and 3.2 ports and work across desktops, laptops, servers, docking stations, printers, routers, POS terminals, kiosks, and other standard Type-A devices. The compact, metal design keeps the port accessible when unlocked and fully closed when blocked, minimizing interference with nearby ports.

• Great for shared workspaces, schools, retail kiosks, or data centers where port access should be controlled
• Effective in preventing thumb drives from being connected without authorization, and discouraging unapproved charging
• Offers a practical, hardware-based layer of protection alongside software security measures
