In cabinetmaking, frameless construction of cabinets uses flat panels of engineered wood — usually particle board, plywood or medium-density fibreboard — rather than the older frame and panel construction.
A common construction method for frameless cabinets originated in Europe after World War II and is known as the 32-mm system or European system.
[1] The name comes from the 32-millimetre spacing between the system holes used for construction and installation of hardware typically used for doors, drawers and shelves.
Frameless cabinets are usually edgebanded to finish the front faces.
By eliminating the front frame, there is more room to place large objects inside, and more usable space.
