Frequently Asked Questions
What is the difference between 280611.1 and 280611.2?
Both are Siegmund Professional Screw Clamps with vertical action toggle, rated at 2.5 kN maximum clamping force and 310 mm high. 280611.1 is the straight version (222 mm wide, 2.86 kg). 280611.2 is the 45°/90° version (2.5 kg).
Why choose a toggle screw clamp over a fast tension clamp?
Siegmund says the special feature of this screw clamp is a stronger clamping stroke compared with conventional fast tension clamps, and that clamping vertically from above gives maximum clamping stability. The height is set quickly with the handwheel on the cast iron cross.
Can I replace worn parts instead of buying a new clamp?
Yes. Siegmund sells the spare parts individually. Its parts list for 280611.1 is 280632.N, 280631.N, 280617, 280662.2, 280618.N, 009902.1 and 280657.1.N; for 280611.2 it is 280633.N, 280617.2, 280662.2, 289109.N.Set, 289108.N, 009902.1 and 280657.1.N. Email sales@bthsales.ca with the part number you need.
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.
