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.

Frequently Asked Questions
Where does a flex stop work best?
Siegmund says the rounded clamping sides let it be used in corners as well as on freeform stop surfaces, and that the Flex Stop is favoured when working with stainless steel and in confined spaces.
Aluminum or galvanized steel?
Siegmund favours the aluminum Flex Stop for stainless steel work. It lists the 25x156 aluminum (280412) at 0.3 kg and the 25x140 galvanized steel (280416) at 0.37 kg, both with a 100 mm adjusting range.
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.
