Ringbook mechanisms – What are the sizes?

Ringbook mechanisms can be ordered in various 2-rings or 4-rings models:

  • D-shaped rings (one straight side, one bend side)
  • Q-shaped rings (both sides straight, rectangular shape)
  • O-shaped rings (round mechanic)
  • Lever arch (for folders, 2-rings)

Which materials exist?

Our mechanisms available from stock are nickel plated. On demand, we can also powder coat the mechanisms in every RAL colour. For more information on price and delivery times of customized mechanisms please contact us.

Ringbook mechanisms – Usage & assembly

O-shaped rings are often used in standard folders. The round shape eases the turning of pages. D-shaped rings are more suitable for larger folders for example since their capacity is bigger (a higher fill).

The straight side prevents the documents from falling out of the rings upon opening. Q-shaped rings are very stable and therefore most suitable for heavy applications.

These too have a higher fill without any documents or sample falling out upon opening the rings, rendered possible by the rectangular shape.

All ringbook mechanisms are assembled in folders by means of automatic rivers. These permanent rivets can be fixed by means of a press and matching tooling. More information on automatic rivets can be found on a separate page.

Lever arches differ from the other ringbook mechanisms. These always consist of 2 rings combined with a lever for easy opening and closing. They are mainly used in folders, by means of automatic rivets.
