Extra protection. Good stuff. I am using continuously. Thx ### ⭐⭐⭐⭐ Do what they say *by A***T on 25 August 2021* They work, very difficult to remove without the key and if the socket is slightly set back they are close to impossible without the key. The only issue is there are only 4 or 5 keys available and they are easy to obtain so any body determined to get into your system will not be stopped. Especially if premeditated. ## Frequently Bought Together - Lindy USB Port Blocker - Pack of 4, White (40454) - Lindy USB Port Blocker - Pack of 10 - White 40464 - LINDY USB Type C Port Blocker Key, White - Pack of 4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/48241036-usb-type-a-port-blocker-key-pack-of-4-blockers](https://www.desertcart.sk/products/48241036-usb-type-a-port-blocker-key-pack-of-4-blockers) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-24*
