Type 4

This model has two independent expanding clamps allowing coaxial alignment of two hollow cylindrical components of different diameters.

The first expanding clamp is inserted and clamped inside the pipe by means of the knob. Then the other weld part (eg the flange) is placed over the top expanding clamp and clamped by means of the hand-bar.

Specially suited to heavier parts than type 3 (above)
