This drawer set is very high quality but due to the cabinet frame, we couldn’t fit it through the opening. My husband had to “hack” it. With the drawers removed, we sawed just a line in the bottom wood pieces & unscrewed the metal bracket in the top- essentially making a left half and a right half of the frame. We could then insert it through the cabinet opening and screwed it in place. You don’t see where we had to cut the wood because the bottom drawer covers it and the frame itself fits properly to the cabinet area just not be opening.  I’m glad we didn’t have to return it as the drawers are absolutely perfect except just being a quarter inch too wide for my cabinet frame.
