Open USB Ports Are an Invitation You Didn't Send
An employee plugs in an unknown thumb drive. A student syncs a personal phone at a school computer. A customer leans across the counter at an unattended POS terminal. A rogue USB cable at a public charging station tries to pull data the moment a laptop plugs in. Every open USB-A port is a pathway for malware, data theft, tampering, and juice jacking, and most desktops, servers, and shared machines still have several.
The Two-Point Lock System, Built to Make Attackers Work Harder
Most USB port blockers rely on a single release point. Ours doesn't. The Two-Point Lock System uses two independent latches that must both engage at the same time for the lock to open. The included security key is shaped precisely to this mechanism. The result: a more secure physical lock, resistant to tampering, positioned as the advanced tier in the PortPlugs port protection range.
Zinc Alloy Body. No Nonsense.
Solid zinc alloy metal. Corrosion-resistant. Built to sit flush inside the port and hold tight against hand or tool removal. Removes cleanly with the key, no port damage. RoHS compliant. Ready for homes, offices, servers, kiosks, and anywhere else an open USB-A port is a problem you'd rather not have.
Works on Every USB-A Port You'll Meet
USB-A 2.0. USB-A 3.0. USB-A 3.1. USB-A 3.2. Desktops, laptops, servers, docking stations, printers, routers, POS terminals, kiosks. If it has a Type-A port, PortPlugs fit. Deploy them in offices, classrooms, libraries, retail counters, server rooms, reception desks, or any shared workstation where an open port is a risk you've been ignoring.
Shoppers Often Ask
How is the Two-Point Lock System different from other USB locks? It uses two independent release latches instead of a single rotating point, delivering a more secure mechanical lock. Does the key come with it? Yes. Every pack ships in a reusable pouch with one matching security key. Is the key metal or plastic? Durable plastic, shaped precisely to the two-point mechanism. Will this damage my USB-A port? No, the zinc alloy body is sized to USB-A tolerances and the key-driven release avoids port damage. Does this deter juice jacking? Yes. By physically blocking the port, it stops rogue-cable attacks on personal laptops and unauthorized personal-device charging or data syncing on company computers. Is this RoHS compliant? Yes.
