These are some heavy duty 10 gauge 4 conductor cords for 480V. Needed to keep them on the dock but didn't have a good place to put them. Wanted to hang them up but there is no wall space. I wanted to use this railing but I couldn't figure out how I could possibly mount something horizontal to it and yet give it some space. So I used compression, with carriage bolts and some 2x6, and long threaded rod for the hangers. This has worked out great for many years.
