Not bad electrically for a single lock-on. I would suggest at least four location for power and common feeds for that loop.
Too bad you couldn't get the angled table into the space.
Have you ever tried spreading the rail from the bottom and inserting a stripped end of wire for a feed? A quick dab of solder makes it nice. A thin blade flat screwdriver and then rotated a little. I also like the lock-ons that press up into the rail bottom in the same fashion. The side clip dealies seam shaky.
