Port blocker Smartkeeper OM03BK MicroSD card USB Type-A Black
Port blocker Smartkeeper OM03BK MicroSD card USB Type-A Black
The Smartkeeper OM03BK is a removable port blocker for MicroSD and USB Type-A ports in black. Once the Charging Lock is engaged, data transfer through the USB port is disabled while charging remains possible. The blocker installs into the port to prevent unauthorized physical access and can be removed with the Basic Port Lock Key, which is compatible with other Essential EssK products of the same colour. The device is intended for controlling use of USB ports by external vendors, visitors or employees and serves as a compact physical security measure.
The port blocker disables data exchange while allowing power delivery, reducing the risk of data theft or malware infection via USB. Its removable design with a standard Basic Port Lock Key enables centralized control and consistent keying across compatible products. The compact black design is easy to install and does not require software, providing a simple, physical layer of protection for ports.
Insert the Smartkeeper OM03BK into the MicroSD or USB Type-A port until it seats securely. To engage the Charging Lock, ensure the blocker is fully inserted; this disables data lines while allowing the port to supply power for charging. To remove the blocker, insert the Basic Port Lock Key and turn or pull as instructed by the key manufacturer. No software installation is required.
Use the Basic Port Lock Key stored securely by authorized personnel. Regularly inspect installed blockers for physical damage and replace if worn. Use consistent keying across devices to simplify management and record which ports are protected.
