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.
- Siegmund System 28: fits every System 28 Siegmund table, including the Professional Extreme 8.7 and 8.8 PLUS tables listed on bthsales.ca; on a System 16 table it needs Siegmund's Reduction Bushing 28->16 (000546, suits boreholes and elongated holes) with System 16 bolts, or the Combination Fast Clamping Bolt 28->16 (000520); neither is listed on bthsales.ca.
- Works with: other Siegmund System 28 clamps, bolts, stops, squares and U-squares on the same table.
- Care & grounding: anti-spatter spray, CleanBasic cleaner, Ground Connection Comfort (S16/S28).

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
Do I need the left or the right version?
The two versions differ only in which side the stop is on: 280164.N has the stop on the left and 280165.N on the right. Siegmund lists the same size (276 x 95 x 500 mm, 27 mm material thickness) for both and recommends this square as a pair.
Can the square be fixed or adjusted?
Both. Siegmund says this 500 G square can be fixed and variably adjusted thanks to the combination of system bores and the elongated hole, and that it can also be used as a table extension.
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.
