Review on FRMSAET Furniture Accessories Office Product Suits Hardware 20/24/30 Inches Keyboard Drawer Tray Wood Holder Under Desk Adjustable Height Platform. (20 Inches, Black) by Erica Johnson

Per other reviews I wasn't sure about the side rails and their stability. They were all right! The plastic bits in the holes just push down the hole when you go to use the screws that came with it! They didn't even glue em in, lame. But you can either go get longer wood screws like some did, or just super glue it all to the side then screw it in! Thats what I did, put a little extra super glue in the hole before the screw placement to make it stronger too. Let it set a day, then installed it under my desk. I needed a couple extra hands to do so, you could also make do with a couple wide mouth wood clamps. Overall, easy install! Great look too. I got the 30" width for added room to make adjustments as I desire, could have also gone with the middle length. It's already taking up the whole underside of this 47" desk, might as well make it look nice and even too.
