General Information

This model has two independent expanding clamps, allowing coaxial alignment of two hollow cylindrical components of different diameters. The bottom expanding clamp is inserted and clamped in the pipe by means of the knob. Then the other part (e.g. a flange) is placed over the top expanding clamp and clamped by means of the hand-bar. Compared with model 3a. This model is specially suited for heavy parts. Automatic diameter compensation.

In order to prevent electrolytic corrosion, we recommend the versions with stainless steel support rails (VA 1.4301).
