"These low profile cam action clamps and stops have a holding force of 3900N and have fingers that push the workpiece down before clamping, even on castings that have negative draft! The stops are mounted with special screws to ensure high precision locating. The spring steel clamping element rotates around an eccentric insert that provides 1.2mm of clamping in all directions. Stops and clamps are available in low profile and raised versions. The single stop with only one rigid stop is used for pieces over 44.5mm long. The double stop with 2 rigid stops is used for small size pieces."
