Information

Ball jointed levelling feet GN 638 are low cost components. They can be used for clamping operations or for load bearing purposes.

Another good feature is a smaller size ball diameter than the trunk of the threaded stud.

As a result the studs can be screwed into position from the ball side. The ball end can easily be hammered in and also dismantled.

Details regarding the static load capacity have been established by a series of tests but are indicative only. For these tests the loads have been placed vertically and centrally over the stud. At the measured load of 3500 N there was no remaining deformation visible on the level-ling pad nor was there any breakage.

A combination of ball jointed levelling feet GN 638 with any handle component will give useful clamping alternatives.
