Frequently Asked Questions
What is the difference from the adapter with hole pattern (2-280715)?
2-280715 is pre-drilled for 32x19 mm / 37 mm toggle clamps. The blank has no hole pattern, so you can fix other clamps or devices to it.
Will it fit a System 16 table?
No. It is made for 28 mm bores; System 16 tables use Ø 16 mm bores.
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.
