@Rozi1295 please see if this photo is sufficient for you. It shows the central web and the upper slot for the top cam band. Only the lower cam band goes through the plate, the upper cam band goers though the web as shown. I add a Fastex buckle and a piece of one inch strap for a tank neck strap to add further stability. The strap is attached using a barrel nut (sex screw) in the upper most hole in the wing/plate.
