4 Pack Black Chassis Hard Drive Mounting Plastic Rails Durable Anti-Scratch HDD Mount Rails for Desktop Computer Cases

I'll preface my review with saying that I wasn't aware these were Cooler Master branded hard drive mounting rails. The product images on Amazon confirm this upon further analysis. I bought these expecting generic china mounting rails, it was a nice surprise to see the CM logo on them. The rails themselves are nice, have rubber mounts for the screws and seem high enough quality for it's purpose. However, beware the included "screws"! They aren't screws at all! The included mounting "screws" have no philips engraving for use with a screwdriver, nor do the "screws" actually have any threading to them; they are threadless! Due to the way the included screws have been designed, they are essentially push pins that resemble smaller-than-usual thumb screws (again, no threads on them). To use these you must friction fit them into your storage drive by inserting them in the rubber screw holes. You have to press quite a bit for it to really seat in there and not back out. Not extremely difficult but if you use your finger/nail it is discomforting and not the easiest. To mount the rails and included screws to your drive I would recommend using a simple pen like I have shown in my product images. That should give ample leverage to seat the mounting pins in securely and easily. To summarize my review, I think the plastic rails themselves are okay and will certainly get the job done. I am not unhappy with my purchase, however I think for the money the mounting pins that are included are somewhat disappointing. They are technically "tool-less", but are slightly finicky and due to their design I think the only way to remove the mounting pins is going to require pulling the plastic rails and hoping it pulls the pins out with it. I am giving this product 5 stars out of 5 stars, mostly because I will likely purchase another set of these in the future and there is no critical design flaw that would stop you from using actual screws. I would like to see this product be a dollar or two cheaper though. While the product gets 5 stars, the ease of use and installation gets only 4 due to the mounting pins. Read more

Not much to say they pin into the side of your HDD's and they hold them to slide in to lock in place. They haven't broke, they don't have an issue locking into the track. They are priced well. They are not too thick for any tracks but are not thin to break at the same time Read more

Hard to find but perfect for this old box. Read more

While the materials are good these rails are incompatible with the Zalman Z1 ATX Mid Tower case. The rails are too long for the enclosure in the case. I'm writing this in case someone is searching for this particular model. Regardless of the model of your case, the rails are well constructed and my only criticism would be that the bolts that go into the screw holes in the HDD might be a little hard to fasten into the drive without the help of any tools.

Needed these for a hard drive install that didn't come with any equipment. Despite their simple design they were super effective and the system has been up and running every since. Read more

Believe it or not but an object this simple actually arrived unassembled. The metal pins which align and secure the HDD with the rails are not placed in the rails to begin with. The packaging is an opaque bag, so if you aren't aware of this it's entirely possible to toss the bag before realizing you've thrown away critical pieces of these rails. Assembly is really not a problem. You just put the pins into the holes. Some significant force is needed, however, and if you don't have the strongest fingers this may cause issues. Just keep an eye out for those pins dropping. They are very small. Read more

Read reviews and found it was actually the maker of the case I had. It fits the hard drive perfectly and holds it in place. I also read the "screws" aren't screws, which they aren't. Instead of trying to push them, as the reviewer did, I was able to find actual screws I had left over from numerous other builds that fit and worked as I wanted them to. Read more

It worked perfectly well for me. Read more
