Frequently Asked Questions
Which parts make up a Multi Clamp Tower?
Siegmund builds it from a plate (280646 small or 280646.5 large), a vertical pipe (280646.1 to 280646.4), this cast iron cross with handwheel and a horizontal bar (280638.N, 280638.1.N or 280638.2.N). The table top and vertical pipe are bolted together.
How is the tower fastened to the table?
Siegmund says bolts quickly fasten Multi Clamp Towers to tables or other components, creating a sturdy support surface.
Will it fit other 28 mm welding tables?
Yes, if the table has Ø28 mm bores on a 100 mm grid. Check the bore diameter and grid before ordering. Compatible tables from other manufacturers are often made from different materials and to different standards, so quality varies by manufacturer, compared with Siegmund's X8.7 tool steel.
