Frequently Asked Questions
Where does the aluminum flex stop work best?
Siegmund says its radiused clamping sides let it be used in corners as well as on freeform stop surfaces, and that it is favoured when working with stainless steel and in confined spaces.
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.
