Sorry I don't have pictures. I bought the 3/8 size and the 12 pack. Worked out perfect for my 16 by 6.5 utility trailer. I put them at the deck level so they are just below the wood. In front of the dual axle on both sides three D rings evenly spaced. Across the front same level and spacing are three more . On both sides behind the axles only room for one D ring but works out good for the count. The last one I welded it to the center rear underneath on the main cross beam. Now I can secure a load from all four sides. I thought the 3/8 might be to heavy but worked out perfect. Been wanting to do it for years, Thank You. Keven
