These weight plate storage mounts fit the vertical racks perfectly. They are secure once attached and are not going anywhere. My only issues might be the fact that due to how they are mounted, you cannot have the actual mount on the highest hole on the rack due to the way they attach and the highest hole being needed for one of the bolts (so the mount rests at the second hole from the top) Also, if you have your rack in a "nook" or otherwise tighter space, the weight plates do make getting the dumbbells off a bit more difficult, but nothing that one can't eventually get used to. Lastly, the included directions say that there should have been a wrench included in with the mounts and the bolts/nuts/washers, but I did not have a wrench in the box. That stated, there is nothing "strange" about the bolts or nuts, so the availability of a basic tool kit worked fine.

Creates storage options for getting things off the floor. I put two on my alpha elite 5 tier dumbbell rack for my change plates. I don’t love that you can’t push the plates all the way back and that larger weights would interfere with getting to the dumbbells. The assembly process is simple and well thought out.

Easy to set up and holds good amount of weight. Makes my home gym look more organized!

Good storage for smaller plates. It does not work well with large plates or bumper plates as it can interfere with dumbbells and/or the rack bracket

This was easy to attach to the rack and works really well. My weight plates arw off the ground now. I recommend this.
