Yep! measured some this morning, youre hands were smaller then. Now I didn't use calipers, just an old steel tape, it's about 3 inches from the base ( car side ) to the center of the grab and less than 2 3/4 inch clearance between. It was the same for drop type grabs and the straight ones welded onto angle irons to form a ladder so a clearance of 0.030" would be right on for models. I measured a few on flat cars and a few on Box's they were all the same.I seem to recall more room than that when I used to climb on cars,
