Hanging new LED's

[RRaider]

I have a 156G tank 60x24x25 that I'm going to be installing three LED fixtures over. I do have a canopy and it does have a top, however the top is just an open frame that allows me to switch lights easily. When I had t5's I built a frame the right size for the bulbs and screwed it to the underside of the canopy frame. When I switched to MH I built frames that hold the MH reflectors and sit in the opening of the canopy lid. This allows me to slide the MH's side to side to adjust where the lighting lands in the tank. The front of the canopy hinges up and the front/top are also hinged at the back of the canopy so the whole front/top can be raised to allow better access to the tank.


Anyway I have two RapidLed Dimmable Onyx fixtures coming and one AI Hydra. The Onyx fixtures have two holes on each end for hanging and the Hydra has on hole in the center of each end. I'd like to be able to turn each fixture 90 degrees and slide them side to side. I plan on hanging an onyx on each end and the Hydra in the center.

Here is a rough paint sketch.

How would you do this?

Quick thought flat aluminum barstock attached to square barstock that is threaded onto a square rail...

Sq and barstock are attached to each other w/ a bolt that acts a s a pivot..
sq rail goes back and forth across flat rail

Drill larger hole in one side of square stock.Smaller hole opposite.. drop a bolt through this. Add a spacer between sq and bar stock. Drill hole through bar stock (attach lights to this any way you want ) Slide onto bolt. Attach nut to bottom. for safety you could drill a hole through the bolt and put in cotter pin.. Will hold the bolt up in case of loosening

Attach square rail L/R in hood Slide the sq stock onto that.. Done..

Oh you could use hangers so you wouldn't have to actually attach the rail
Should be somewhat self explanatory..
