Frequently Asked Questions
Which lengths does Siegmund make in this section?
Siegmund lists the System 28 400x200 U-square in lengths of 500, 1000, 1200, 1500, 2000, 2400, 3000, 4000 mm. Weight rises with length (500x400x200 107 kg; 2000x400x200 336 kg; 4000x400x200 641 kg, Siegmund). This one is 1200 mm long and weighs 216 kg.
How is it fixed to the table?
Siegmund says the U-square is bolted to the table with connecting bolts. Siegmund designs its System 28 Connecting Bolt (280560.N) as a fixed long-term connection between large components such as tables and U-shaped squares, and says it should not be used in elongated holes.
Does it need support as a table extension?
Yes. Siegmund says that when a U-square is used as a table extension exceeding 1,000 mm, it has to be supported by a table leg, and that from a length of 500 mm all U-squares have mounting holes on the back to attach table legs.
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.
