These are blocks that are placed on the plate to prolong the flux. They enable through holes to be drilled without damaging the plate surface. Their height should be around 15-20 mm.

These have a protuberance that serves as an end stop, to aid the machining processes.

These are blocks equipped with springs to enable the poles to adjust to an irregular part surface.

Three fixed pole shoes are placed, forming the largest possible triangle underneath the part to be clamped, and the rest of the poles are filled with the mobile pole shoes, forming a V between each two.
