Compatibility
- Fits: Siegmund System 28 tables and tools; Siegmund says it can be used universally with 28 mm boreholes. Also fits other 28 mm system welding tables with Ø 28 mm bores on a 100 mm grid.
- Not compatible with: System 16 (Ø 16 mm bores) tables and tools.
- Works with: Vertical Toggle Clamp with Adapter CS280791, Horizontal Toggle Clamp with Adapter CS280793, Vertical Toggle Clamp 009082, Horizontal Toggle Clamp 009083.
- Also matches (Kifix): the Kifix KF-017 DB and Kifix KF-211 DB vertical toggle clamps (flanged base) have a 32 × 19 mm base hole pattern, which matches this adapter's hole pattern, so they mount on Siegmund System 28 welding tables with 280715 or 280715.1.
What's included
1 × adapter in the selected height (burnished, with integrated O-ring). Toggle clamp and screws are not included.
Typical uses
- Mounting a vertical or horizontal toggle clamp at any bore position on the table
- Raising a toggle clamp to the workpiece with the taller 280715.1 (Ø 50 / 40) version
- Repeatable fixtures that can be removed and re-set in seconds
- Light to heavy workpieces: Siegmund describes System 28 as ideal for light to heavy components and designed for maximum clamping forces, multi-ton structures and high distortion forces

FAQ
Which toggle clamps fit the 280715 adapter?
Toggle clamps with a 32x19 mm or 37 mm hole pattern, per Siegmund.
Which height should I choose?
Pick the height that brings the clamp to your workpiece. Siegmund lists 280715 at 29.5 mm high and 280715.1 at 55 mm high.
Does the adapter come with a clamp?
No. It is the adapter only; toggle clamps are sold separately.
Will it fit a System 16 table?
No. It is made for 28 mm bores. Siegmund makes a separate System 16 version (item 160715) for Ø 16 mm bores. The 160715 adapter is available on request; contact sales@bthsales.ca.
Will it fit other 28 mm welding tables?
Yes, if the table has Ø 28 mm bores. Siegmund System 28 tables have Ø 28 mm bores on a 100 × 100 mm (or diagonal) grid and a material thickness of about 24.5–27 mm, so check your table's bore diameter and plate thickness before ordering. Ask us if you are unsure.
