Item 800390.X7: Siegmund Square U-Shape 2000x200x200 Premium Light, plasma nitrided, for System 28 welding tables with Ø28 mm bores. Siegmund says Premium Light's harder but thinner X8.7 tool steel (15 mm) saves up to 40% weight; it serves as a table extension, for vertical setups and to connect two welding tables.

Frequently Asked Questions
Which lengths does Siegmund make in this section?
Siegmund lists the System 28 Premium Light 200x200 U-square in lengths of 500, 1000, 1500, 2000 mm. Weight rises with length (500x200x200 42 kg; 1000x200x200 76 kg; 1500x200x200 110 kg; 2000x200x200 143 kg, Siegmund). This one is 2000 mm long and weighs 143 kg.
How is it fixed to a standard table?
Siegmund says the Premium Light U-squares are fastened to the table with Connecting Bolt 800562, which is designed to connect Siegmund tables and components with 25 mm material thickness to Premium Light components with 15 mm material thickness.
Do I need anything extra to clamp on Premium Light?
Yes. Siegmund says that for clamping on Premium Light with a clamping bolt, the Adjusting Ring 280653.N is required to compensate for the lower material thickness.
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.
