Very nice. The factory cross bars are terrible for hauling a canoe. They are not wide enough and sit flush with the plastic fairing, so the canoe ends up riding on the fairing instead of the front crossbar. I am about to follow your lead, but I am having trouble sourcing solid uni/super strut locally. I've only checked Lowes and Home Depot, but everything they had was slotted. Where did you source yours?

I lucked out and found my solid stainless strut channel at a freight damage store. If I had realized at the time how good of a deal it was, I would have bought more as I think I paid about ten bucks for it.

Since that doesn't help you at all, I would suggest looking at electrical or plumbing supply companies. You could also try ordering online from McMaster Carr:

I think aesthetically the black powder coated solid strut would look good. And you certainly don't have to use the solid channel, although I prefer it because when you slide the spring nuts into various configurations the springs don't pop out of the bottom of the channel.

Dang that's a good deal! I ended finding it last night at Grainger, but I had to order it and have it delivered to the store. I was able to get black powder coated in 5' sections. The issue with the spring nuts is exactly why I wanted the solid channel. Also, I believe it will look a bit more finished.
