Ron,
While the channel on this raceway resembles uni strut, I should have said that is is not.
This channel is much shallower and wider.
Here is a picture of a standard strut-nut and the insert I need for this channel.
Both the channel and insert are aluminum.
That does look awesome, unfortunately it is designed for the standard uni strut width. This channel is wider. See pic of standard strut-nut above and the insert for this channel.
Thanks,
Joe
