How does this grab the deck? The tool punches a hole in both sides of a low rib and the caddy piece passes right through the deck and hooks onto itself. From these we used wire rope drops to the fixtures, during construction a few guys caught the wire rope drops with the lifts and kept driving. The Caddy piece held fine, the cable would break with a very large noise that scared the heck out of the guy on the lift.

So this isn't a deck with concrete poured over it No, it is the roof deck. No cement, but a little nasty water once in a while. If it was poured I would have shot 1/4" studs directly into the deck with a Hilti.

Bob: My hat is off to you again. Have not seen the Caddy item; am familiar with Hilti methods with a mechanic with a good aim!
The wire rope you used, was it a Caddy item thats very 'adjustable'?

For whatever it is worth the American Electricians Handbook recommends using three supports for an 8' long suspended light fixture. It is not the code book, but it does get referenced in an alot of the commercial specifications I have come across. And makes for a pretty good guideline to boot.

That would have changed my hanger count from about 600 to 1,800, I don't see me doing that. For what it's worth these where 8' 4 lamp T-8 fixtures with electronic ballasts. I think the 4 lamps weigh more than the entire fixture.
