This was/is in the Photo Gallery, & I moved it here to have some thoughts & discussion.
It is 'bolted' to the rail via two 1/4-20 machine screws, and the conduits are the rest of the 'support'.
It is not 'new' and seems to have been there for some time.
There's another pic of the troff that has clearance issues.
Please use the link, until I move the pic here.
