Items 280210, 280211 and 280212: Siegmund Clamping Bridge 2P and 3P for screw clamps, System 28, plus the spare spherical pin. A bridge lets one screw clamp hold at two or three points, reaches awkward spots, and its pendulum compensation copes with uneven surfaces. BTH Sales is the exclusive Canadian importer of Siegmund.

Compatibility
- Fits: Siegmund System 28 welding tables and tooling with Ø28 mm bores on a 100 mm grid. It works with Siegmund System 28 screw clamps, including on other 28 mm system welding tables with Ø28 mm bores. 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.
- 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.
Typical uses
- Positions that are difficult to access (Siegmund).
- Clamping several components at once: 2 points with the 2P, 3 points in three dimensions with the 3P (Siegmund).
- Uneven surfaces, with pendulum compensation (Siegmund).
- Siegmund describes System 28 as ideal for light to heavy components and designed for maximum clamping forces, multi-ton structures and high distortion forces.

Frequently Asked Questions
Should I choose the 2P or the 3P clamping bridge?
Siegmund says the 2P clamps at 2 points simultaneously, while the 3P clamps at 3 points and, thanks to its three-dimensionality, can clamp in three dimensions. Both are 170 x 35 x 20 mm; the 2P is 0.51 kg and the 3P is 0.58 kg.
Does the bridge work on uneven parts?
Yes. Siegmund says clamping on uneven surfaces is possible with pendulum compensation, and the spherical pins can be shifted quickly.
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.
