The distance between the slots center to center is 3.35 inches using my dial calipers. Slot width is .35 inches, length is 2.25 inches. Vertical distance between slots is 4.55 bottom of top slot to top of bottom slot. And they all (HOG wings) fit real well on a DSS plate. I still have one on my 32lb wing
in addition to my HOG plates The bands I have on there are something I picked up at DEMA to try.
