Frequently Asked Questions
Should I choose the nitrided or the chromed version?
Siegmund offers the chromed version (280105.C) for work on measuring tables, working with aluminum and TIG welding. Both are 75 x 50 x 75 mm with 25 mm material thickness and 1 kg.
How do I build a height-adjustable support?
Siegmund combines the 75 L with a Stop and Clamping Square that has an elongated hole, for example the 175 WL (280111.N), or with the 175 SL and 175 L or 175 VL.
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.
