The AMPCOM USB-A Port Blocker is a physical security solution that locks down 100 USB-A ports across your entire device fleet with one purchase. Each insert is crafted from nickel-plated stainless steel — not zinc alloy, not basic metal, not plastic — delivering superior corrosion resistance and structural integrity in harsh environments. The patented dual-keyhole mechanism is what sets it apart: two engagement points distribute removal force evenly so authorized IT staff can unlock ports thousands of times without damaging the USB-A port wall or wearing down the key

For IT administrators managing open-plan offices: a visual security audit takes seconds, not hours.
For data center operators: the nickel-plated stainless steel body handles the heat, vibration, and humidity of server rack environments where plastic blockers would crack within months and uncoated metal would eventually rust.
For business travelers: toss a handful of blockers and a key into your laptop bag and physically lock hotel business center and airport lounge USB-A ports before plugging in.
For schools and libraries: prevent students and patrons from inserting unknown USB drives that could carry malware onto public-access computers.
