Review: Wow! - I found this brand recommended on a forum discussion about replacement lock options for their firearm security cabinet. This thing fits my Stack-on/Sentinel cabinet absolutely perfectly. When I ordered it, I was a little worried it wouldn't fit, as some of these, mine included, have the lock recessed slightly into the door. My worries were unnecessary. The thing couldn't fit better if it was custom made. The knob is solid machined aluminum, anodized black, and looks really good. It's reeded surface make it easy to turn against the weight of the 2"x5" steel plate cam on the other side. The only downside is that its tapered shape makes it difficult to use to pull open the door the way you could with the key it was replacing, so I had to install a handle above it as the door is flush fitting and there was nothing else to pull on. I probably could have used a nylon strap or something, but I had a black drawer pull lying around, so I used that, and it looks nice. Compared to having to go dig out the key every time I need to get in the cabinet, the combo lock is great. Some might say that a three digit combo isn't exactly secure, but given that it's replacing a wafer lock, I think its actually a step up. Yes, someone will eventually brute force the combination by trying them one by one, but the previous lock could be picked in about five seconds by someone who knows what they're doing too. The point isn't to keep someone nefarious completely out, it's to slow them down enough that they're less likely to risk taking the time. I don't have a family at home, so I don't need to worry about a bored and curious person with far more time than a burglar playing with it until it opens either. This is to keep casual visitors out more than anything. I wouldn't have bought a cheap steel cabinet if my security needs were greater. I highly recommend this to any other Stack-On/Sentinel owners who need to replace their lock due to a broken or lost key, or just don't want to deal with them anymore. I can get into my cabinet in seconds now as opposed to several minutes before, and locking up when I'm done is almost instantaneous.
Review: Works perfect - Got this to replace the unlockable knob on my truck bed's storage bin (2021 Ford Maverick). Took a little shaving down of the truck box, but this went in perfect and I can now lock that box with a code. Great extra parts that come with it made it easy to install.

*by E***L on November 5, 2024*

### ⭐⭐⭐⭐⭐ High Quality, Same as Tuffy Lock
*by J***N on January 8, 2026*

This is the exact same thing as the lock Tuffy sells but without the branding so the price is lower. I used this on my Bestop under seat lock box. I had to reuse the original lockbar other than that it worked flawlessly.
