Combi mechanisms come with a variety of advantages. This file mechanism combines the benefits of an R-shape and a Q-shape ring binder mechanism. So D-shape ring binder mechanisms are also known as combi mechanisms. With this type of file mechanism, it is very easy to file and remove the individual pages. This is made possible by the half round rings in the front of the ring mechanism. Leafing back through the pages is also very convenient with this kind of file mechanism. So the rounded rings on the mechanism have all the advantages of this kind of ring binder mechanism. At the same time, combi mechanisms have the advantage that the straight bracket on the inside means the edges of the pages line up straight. This design also gives excellent utilisation of the full capacity of the bracket.

This makes combi mechanisms particularly popular and are frequently used in a variety of industries. D-shape mechanisms are available in various designs and sizes. Depending on the volume, format and number of holes in the material to be filed, you can select the number of rings and spacing. The 2 ring combi-mechanism version allows individual pages to be put in or taken out quickly. A range of dimensions is available for this kind of ring binder mechanism. Choose the combi mechanism you would like according to your own preferences and requirements, in the quantity and ring size which suits you best. The D-shape ring binder mechanisms with four rings are also available in a range of designs. In this kind of file mechanism, the material is held in a particularly stable way.

The robust D-shape 4 ring mechanism protects the filed sheets particularly well from being pulled out. Naturally the special 3 ring D-shape mechanism is also available. Combi mechanisms are a very common form of ring book mechanism. In order to exploit all the advantages of this kind of file mechanism, you need to rely on the quality of the components used. High quality file mechanisms using the combi design facilitate frequent opening and closing while securing the sheets reliably and consistently.
