I didn't like the contact pressure of the cable/vinyl tube and the lightening holes caused by the use of a adel clamp on adjacent sides of the lightening holes as the cable passed through them. I removed one of the clamps from each of the holes and allowed the other side to be free. This still secured the cable and vinyl tubing but reduced the side forces of the cable on the sides as it passed through the holes. I also increased the vinyl tube size to 5/8" O.D. and installed larger clamps. This will allow for future addition of wires to the cable run.
