Port blocker Smartkeeper BL04P1GN
The Smartkeeper BL04P1GN is a USB Type-B port blocker designed to secure USB Type-B ports on devices by preventing unauthorized connections. Constructed from durable green plastic, the blocker has compact dimensions of 130 mm width, 205 mm depth and 10 mm height, and a lightweight build that enables unobtrusive permanent or temporary installation. The product is intended for environments where limiting physical access to USB Type-B interfaces reduces risk to data and system integrity.
The port blocker provides a physical barrier to USB Type-B ports without requiring changes to device firmware or software. Its plastic construction resists everyday wear while remaining lightweight. The green colour allows visual identification of protected ports. Low profile dimensions make it compatible with a wide range of equipment layouts and help avoid interference with adjacent connectors.
Align the port blocker with the USB Type-B port on the device and insert it until it sits flush or is secured by the device's port geometry. For temporary use, remove by pulling the blocker straight out to avoid damaging the port. For longer-term installations, ensure the blocker is seated firmly and check that adjacent connectors remain accessible. No software installation or configuration is required.
Use the port blocker where physical prevention of USB Type-B access is sufficient for security policy. Inspect the blocker periodically for signs of wear and replace if the fit becomes loose. Keep spare blockers available for maintenance or device replacement to maintain consistent port protection across equipment.
