Is it suitable for aluminum profiles?
No. Siegmund lists the 280550.1 as not suitable for aluminum profiles. For aluminum, Siegmund offers the Connecting Bolt with collar (280583 to 280585).
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.
