Mastercraft cabinets is a company owned by Elkay. This is one of several companies owned by Elkay that makes cabinets. They offer a modest selection of door styles and finishes but offer some construction upgrades not found on all cabinets. One is the iframe support at the top of the cabinet. Most manufacturers use corner supports, but the iframe is more sturdy when you are handling the cabinets. Once the cabinet is installed, if installed properly, the iframe offers no additional benefits. They also offer a couple of doors in Ash. If you are looking for a quality cabinet, Mastercraft is a good choice.
