Hinge holes and shelf holes are perfectly aligned using the 32 mm system. The hinge plate fits into the adjustable shelf holes.

What does a 32 (mm) millimeter increment have to do with the way a cabinet is built? It’s referred to as a set system or standard in the cabinetry industry. This is a fabrication method that was founded in Europe thus we get the name European style cabinetry. Almost all of the kitchen, bath, laundry, garage, office and wall-unit hardware components, for this style of cupboards, are made to work with the thirty two millimeter system. Industrial machines, relating to the cabinet manufacturing industry, have been invented and continue to evolve around this metric unit of measurement. Most of the cabinet industry hardware such as hinges, hinge plates, drawer slides and decorative handles are designed to correspond with this metric measuring method. Because of this style of manufacturing, large companies are able to mass produce pre-assembled cabinets and sell them through outlets such as Home Depot or Lowes. Also the RTA (or, “ready to assemble”) cabinets that you purchase in a box, often found in Office Depot, Office Max, Walmart, and other department stores, are manufactured using this thirty two millimeter production method.
