The Lindy 40462 is a pack of 10 USB Type-A port blockers, specifically used for physical cybersecurity. These “locks” are inserted into open USB ports to prevent unauthorized access, malware injection (via “Rubber Ducky” style devices), or data theft in sensitive or public environments.

The 40462 model is part of Lindy’s color-coded security system. Please Note: This specific part number is usually for the 10-pack of extra locks ONLY and does not include the required key.

• Security Logic: Each key is color-specific. If you buy the White (Code White) blockers, you must have a White Key to remove them. This allows administrators to “zone” security (e.g., IT has the Blue key, Security has the White key).

• Design: Once inserted, the blocker sits almost flush with the USB port, making it nearly impossible to remove without the matching mechanical key.

• Target Sectors: Widely used in government, military, banking, and education where software-based USB blocking (via Group Policy) is not enough.
