Port type: Designed for standard USB-A receptacles

Keep critical endpoints and shared stations locked down against unauthorized USB devices. This four-pack of Eaton Tripp Lite USB-A port blockers ships with a single reusable key so teams can centrally control who can use physical USB ports. The blockers sit flush in standard USB-A receptacles to avoid snagging in high-traffic environments and require no firmware or software. Install or remove in seconds with the included key; maintain a simple hardware-based control layer that complements your endpoint DLP and access policies. For procurement, the 4-pack with reusable key reduces per-port cost and avoids recurring single-use blockers, simplifying inventory and support for enterprise deployments.

Lock down USB-A ports on shared point-of-sale and kiosk terminals
Control removable media access on corporate desktops in regulated environments

3Require no software or drivers, unlike some electronic lock solutions that increase management overhead
4Deliver predictable per-deployment cost with a 4-pack that simplifies procurement vs single-piece alternatives

What ports do these blockers support?▾

They are designed for standard USB-A receptacles and fit typical Type-A port openings on desktops, thin clients, kiosks, and POS systems.

The pack includes one mechanical reusable key that inserts into each blocker to lock or release the device; keys should be retained by authorized staff for controlled access.

Do the blockers require drivers or software?▾

No. They are hardware-only blockers and install or remove mechanically using the supplied key—no software, firmware, or configuration required.

Can these be used outdoors or in industrial environments?▾
