This is the best hardware you can buy for a keyboard drawer. The drawer my desk came with has beveled edges so it doesn't fit the side brackets that most come with. Basically, this equipment worked perfectly. It was much better than my desk design as the brackets for the underside of the desk were in the drawer so you had to open them all the way to screw them in (which isn't easy). Not only does this one have bottom-mounted drawer brackets, but also outward-facing table brackets that make installation easier when the drawer is in the closed position. It also extends much further than my original and has a nice "soft click" when fully extended or closed. Highly recommended.
