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.
Typical uses
- Infinitely variable stops and supports through the elongated holes (Siegmund).

Frequently Asked Questions
How is the 90 WL different from the 90 L?
Both are 90 x 30 x 90 mm with 12 mm material thickness. Siegmund gives the 90 WL (160111.N, 0.27 kg) elongated holes so it adjusts infinitely in any direction, while the 90 L (160110.N, 0.31 kg) combines a bore with an elongated hole.
Will it fit other 16 mm welding tables?
Yes, if the table has Ø16 mm bores on a 50 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.
