The Lindy 40452 is a USB Type-A port blocker starter kit that includes both the locks and the removal tool. While your previous query mentioned “Code White,” it is important to clarify that Part No. 40452 corresponds to the Blue color-coded system.

This kit is designed for immediate physical security deployment. Unlike the 10-pack of extra locks (which usually lacks a key), this set provides everything needed to secure and later manage four USB ports.

• Security Logic: The Blue Key included in this kit will only work with Blue Locks. It will not unlock White, Pink, Green, or Orange Lindy blockers.

• Tamper Resistance: Once a lock is inserted, it sits flush against the port housing. It is designed to be effectively impossible to remove with fingers or standard tools without damaging the USB port itself.

• Physical Barrier: Prevents the insertion of “BadUSB” devices, unauthorized thumb drives, or smartphone tethering in high-security environments.
