The round 2-fold grid plate 96 is suitable for equipping round machine tables of a medium size with a zero-point clamping system over as large an area as possible. One or two clamping devises can be clamped side by side in it, and it also fits well visually with round machine tables. On the side where the clamping screw is located, the 2-fold plate has a straight surface, that allows the use of the Quick-Lock fastener.
