In the time of switching to new coupling systems in Europe, it is currently a whole tour as a supplier to arrange everything for the customers.
Oilquick, Steelwrist, open-s, Verachtert-CW, Riedlberger, Lehnhoff, Kinshofer, Elzinga, J&B, TGS and various other coupling systems make it top-sport to understand everything, and certainly to have everything in stock, or to have it quickly at the customer.
Rigter Handelsonderneming from Eemnes has quite a bit in stock of open-s adapters and CW-Verachtert systems and behind the workshop there are shelves with all kinds of systems that are used but good.
From CW 70 to CW 55, from CW 55 to CW 40 from and CW 55 to CW 45, most of it is there and otherwise it is welded together from 2 used items.
