The LogiLink USB Port Blocker set is ideal for schools, offices, public computers, and households where it is necessary to prevent accidental or intentional connection of unauthorized USB devices. The locks act as a visible deterrent while reliably protecting ports from dust and mechanical damage.

Installation takes seconds: insert the blocker into the port and you’re done. Unlocking is done with a dedicated key of the same color, which works only with the corresponding locks. The package includes 1 key and 8 blockers, so you can easily secure multiple ports on one or several devices.

• Physical USB blocking – prevents unauthorized connection of flash drives, cables, or peripherals.
• Quick and simple installation – no tools, no software.
• Port protection – reduces wear and the risk of connector damage.
• Visible security – acts as a preventive measure against tampering.
• Key only for matching locks – color-paired system for increased security.
