These are well built and attractive shelf drawers. However, the manufacturer does not understand the concept of rack hole spacing. The rack ears are drilled correctly. However, the box rides high on the ears. So if the drawer is at the bottom of the rack you will need 5 slots for a 4 slot drawer since the top 1/8 inch or so of the drawer invades the next highest overall rack space. Either that, or you'll need to install the next three pieces of hardware unevenly spaced across the drawer (i.e. not using all of the rack space and you can only use one hole on each side to mount the hardware to the drawer's rack). . Not a big deal, but two of the boxes we ordered were also missing the promised rack screws.
