GN 638 Ball jointed levelling feet Steel / Plastic


Product description


Ball jointed levelling feet GN 638 feature 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 3,5 kN there was no remaining deformation visible on the thrust pad nor was there any breakage.
