USB port lock, Alantec WT-BU-03, red, pack of 10 locks with key

The Alantec WT-BU-03 is a red USB port lock supplied as a pack of 10 locks with a matching key. It is a compact physical device that fits into standard USB-A ports to prevent unauthorized insertion of USB storage devices or peripherals. The lock is designed for environments where simple, visible port control is needed to reduce data leakage, limit use of removable media and enforce device access policies without requiring software configuration.

Advantages

The USB port lock offers a straightforward, low-maintenance way to restrict access to USB-A ports. Its bright red color provides clear visual identification of locked ports and the included key allows authorized personnel to unlock ports when needed. Supplied in a pack of ten, the product is suitable for securing multiple workstations or terminals at once. Installation and removal are performed manually without tools, and the design minimizes impact on the surrounding port area.

Suitable for

• Offices and corporate workstations to enforce security policies
• Schools, libraries and public computers to prevent unauthorized file exchange
• Laboratories and testing facilities where controlled device access is required
• Self-service terminals and kiosks to protect ports from tampering
• IT asset management during audits or in shared equipment environments

Key specifications

• Port compatibility: standard USB-A sockets
• Color: red for visual identification
• Quantity: pack of 10 locks with one matching key
• Material: durable polymer construction for repeated use

How to use

Insert the lock into an empty USB-A port until it seats flush with the port face; the mechanism will secure the lock in place. To unlock, insert the supplied key into the lock and turn according to the lock’s engagement direction, then withdraw the lock. Ensure ports are free of connected devices before installation. Keep the key in a secure location and label keys if multiple people require controlled access.

Usage recommendations

Check port alignment and cleanliness before installation to avoid debris trapping. Use the pack to standardize port protection across multiple devices, and store the key separately from locked equipment to maintain access control. For environments that require logging of access events, combine physical locks with administrative procedures for tracking key use.
