I will start by saying that I love the sturdiness of these glides. They look and feel top quality, but my only issues is in that only one side comes with the locking mechanism. This sort of makes me think that it will rack just a bit when locked.One thing of note is that the rail that attaches to the drawer is not removable from the glides, or at least I could not figure it out and there aren't any instructions that come with these glides. That said there are holes in corresponding places that allow you access to drill and screw holds, but it's an added complexity when mounting.
