PortPlugs USB-A Metal Port Blockers, 50 Pack Security Locks with 2 Removal Keys - Black

Manage physical access to USB-A ports across multiple devices with PortPlugs USB-A Metal Port Blockers. This bulk security set includes 50 metal port blockers and two matching metal removal keys, making it suitable for IT teams, offices, schools, libraries, retailers, and other environments with shared or managed computer equipment.Each blocker features a two-point locking design intended to secure it in a compatible USB-A port until an authorized user removes it with the matching key. The zinc alloy construction and black finish provide a sturdy, discreet option for restricting access to unused ports and helping limit unauthorized connections from flash drives, cables, and other USB peripherals.With 50 blockers in one pack, this set is useful for managing port access across desktop computers, laptops, classroom workstations, reception desks, and other compatible equipment. Keep the two removal keys in a secure location to maintain control over authorized access.Confirm compatibility with your device's USB-A ports before purchasing, as port design and housing may affect fit. These blockers provide a physical access-control measure but cannot independently prevent every cybersecurity threat, including juice jacking. Use them alongside appropriate software security settings and organizational security practices.
