32 mm cabinetmaking system

Shelf with 5 mm (0.20 in) holes at 32 mm (1.3 in) intervals

The 32 mm cabinetmaking system (colloquially called system 32) is a set of principles that has evolved for the production of ready-to-assemble and European-style, frameless construction custom cabinets and other furniture. While not defined by any standardization body, it is in wide use globally, partly owing to IKEA using some of its elements in its furniture. Characteristic are the columns of 5-millimetre (0.20 in) holes with centres at 32-millimetre (1.3 in) intervals.

System 32 enables reconfigurable placement and spacing of shelves, doors, drawers and hardware. Most significantly, it simplifies and harmonizes dimensions, production processes and products for fitting, machine and furniture manufacturers, enabling efficiency and cost reduction.

Properties

The core features are:

  • Distance between hole centres in row: 32 mm (1.3 in)
  • Diameter of each hole: 5 mm (0.20 in)
  • Depth of each hole: 12–14 mm (0.47–0.55 in)
  • Shelf pin length: 15–16 mm (0.59–0.63 in)
  • Shelf pin flange diameter: about 7 millimetres (0.28 in)
  • Distance of first row from front edge: 37 mm (1.5 in)

System 32 includes matching fittings, with which furniture sides may be secured to floors, walls, and adjacent cabinets. Other fittings are available for door bands, drawer guides, clothes racks, floor racks, and other features, and typically mount into one or more of the 5-millimetre (0.20 in) holes otherwise used to support shelf brackets.

Advantages of the system include:

  • Distance from first hole to bottom side of cabinet equals the distance from last hole to top of cabinet. This simplifies setup of single row drilling machines
  • Distances between hole rows are multiples of 32 millimetres (1.3 in). This facilitates assembly of drawer guides
  • Distance of rear hole row to rear edge may be 37 millimetres (1.5 in). This obviates need to retool drilling machine
  • Distance of rear hole row to inner edge of back wall may be 37 millimetres (1.5 in). This facilitates assembly of rear wall supports

History

After World War II, simplification and efficiency was pursued to help speed reconstruction of the vast number of buildings and property destroyed during the war. A spacing of 32 millimetres (1.3 in) evolved because that was the closest multiple drill bits could be placed on a line boring machine due to the size of the gears then available.[1]

Besides the 32-millimetre-based (1.3 in) system, there are other, although less frequently, used systems, such as system 25 and ip20.[2][3][4]

Proprietary variants
