Compatibility
- Fits: Siegmund System 28 welding tables and tooling with Ø28 mm bores on a 100 mm grid. Siegmund System 28 accessories also fit other 28 mm system welding tables with Ø28 mm bores on a 100 mm grid. 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.
- Not compatible: System 16 (Ø16 mm) tables; Siegmund builds each system around one bore size.
- Works with: other Siegmund System 28 clamps, bolts, stops, squares and U-squares on the same table.

Engineering support & demos
Engineering support comes with your purchase: fixture design, layout drawings, CAD and 3D models, site visits and cobot cell planning, handled by Travis Hardcastle at BTH Sales or by Siegmund directly. BTH Sales does not sell cobots; for cobot cells we help with table integration and fixturing (see cobot welding with Siegmund tables). Live demos at our St. Marys showroom are by appointment (book a demo), and we offer video demos if you are outside Ontario. BTH Sales is family-owned, founded in 2001, and has been the exclusive Canadian importer of Siegmund since 2018.

Frequently Asked Questions
How is the clamping block different from a U-square?
Siegmund developed the clamping block in addition to its large range of U- and L-squares. It is a five-sided cube of 400 x 350 x 200 mm with 25 mm material thickness and a 50 mm borehole grid, so you can stop and clamp on five faces.
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.
