Yes the have end caps (well the ones I had did). They are rubi rails with the tubing welded on. The tubing is what makes them enhanced. I had some of these when I got my jeep and sold them. They are over $600 new when I finally found out what they were and looked them up so he has them for a good price. They give a nice little step not much though. They mount in same points as rubi rails and cover the pinch seam. They give a really clean look and they are tough.
Again this is assuming they haven't changed the design over the years.
