Greetings, crew. Does anyone have any experience using half-couplers to rig a light over a bar? I have a difficult lighting position and need to mount the profile directly over a lighting bar, but it's a Selecon 5-13 tube, and weighs almost 40 pounds. Makes me a little uncomfortable. It certainly wouldn't fall with the safety chain, but might roll around the bar. The bar is structurally fixed, not hung. If not a half-coupler, what other method of over-rigging (if any) have people used?
