Frequently Asked Questions Do I need the left or the right version? The two versions differ only in which side the stop is on: 280300.N has the stop on the right and 280301.N on the left. Siegmund lists the same size (300 x 200 x 100 mm, 25 mm material thickness) for both. Can I set variable stops with the support and clamping frame? Yes. Siegmund says both fixed and variable stops are possible because the frame combines system bores with elongated holes, and the 50 mm grid of bores on five sides gives a wide range of combination options. 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.
