More interior space, easy filling and assembly and long service life are just some of the benefits that the E2.1 series has to offer. This new generation of the two-section energy chains was developed to improve on the preceding E2/000 series, which has proved its worth over a period of 15 years. The E2.1 series offers extremely fast filling from the side or from the top – along on the inner or outer radius, using a chain opener or screwdriver. Thanks to these features, the E2.1 is ideal for use in general engineering, woodworking and metalworking industries, and in machine tool construction.
