## Description

NTW net-Lock Locking RJ45 port/dust blocker with color coded keys - Red

Review: Great for Layer-1 security - I got lucky and found a warehouse deal for a 50 pack of these ($19.79, Used-Like New) - not sure if I would have paid the full $75 for a 50 pack. With that said, they get the job done and they do it well. They snap into place VERY securely and there is no removing these things unless you have the key. I have these on my home server rack to primarily keep dust out, they also don’t look half bad. Keeps everything uniform. I could see these being extremely useful in a business or school environment where you need to block those ports out for security reasons. Obviously you could just disable the port in software, but having that extra layer of security definitely doesn’t hurt. I’ve seen some bad reviews where people complain they can’t remove the blocker from the key… just pull it off of the key and you’re good to go. The keys are different for each color, which is also beneficial. Very happy with my set. I did go ahead and take the plunge for another 10-pack at the MSRP to get those last few ports blocked.
Review: I bought 3 different colour packs to differentiate laptops - I bought 3 different colour packs to differentiate general distribution laptops that are the same model, but need to be stored in different areas of our school buildings. They are working really well. Now it's easy to see where laptops need to be returned by their colour code... Yellow... Grade 3 Green... Grade 4 Red... Design Lab Before the port locks we used stickers, but stickers would either fall off or get peeled off. The port locks are highly visible and practically fail-proof. All parties, myself included, are pleased with the purchase.
