what 's the length of the leg?
IS it contain the pad Thk?and also I should measure it to the first point of attachment to shell OR to centroid of the weldment of the wear plate?

Hello aa

The overall length of the leg is from the bottom of the leg (where it meets the ground or the base plate if there is one) to the top most part of the leg itself. The 'distance from node' is the distance of the leg from the bottom weld line to the top of the leg, or the length of the leg to shell weld.
