I have for sale a set of 2 Big Jon 7-position pull pin type solid ready for heavy use rod holders. They are mounted on a solid 1 inch X 3/4 inch and 10 inch long piece of aluminum bar stock which is mounted on a standard 4 inch square Big Jon mounting plate. Each rod holder is held in place by the standard single stud and kept in position by 1/4X20 by 3/4 inch long allen set screw as shown by the additional hole next to the stud. I tried to picture this as best I could. This is a very solid unit which can be used in a variety of ways from downrigger rods to dipseys or planer rods. These rod holders have been used but not abused and are in fine working condition I tried to picture their overall condition in the series of pictures , so please look and judge for your own use.
