USB A Port Blockers 10 Pack, Two Point Zinc Alloy Locks, 1 Key, BlackProduct Overview

Open USB Ports Are an Invitation You Didn't Send

An employee plugs in an unknown thumb drive. A student syncs a personal 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 two-point key is shaped precisely to this mechanism. The result: a more secure physical lock, resistant to tampering, positioned as the advanced tier in the port protection range.

Zinc Alloy Body. No Nonsense.

Solid zinc alloy metal, not plastic. Corrosion-resistant. Built to sit flush inside the port and hold tight against pull attacks. 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, 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 two-point 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.
