cannot find a c channel for roof gutter

yeah, that's what's great about using conduit. someone asked earlier today how much materials cost to build my entire rack. i posted in the build thread for it with a break down of all of the parts....think was less than $100, even with grade 8 everything so you could f*#$% up 4 times on this and still be under $30 lol

stacking should work fine...you'll have 2 bolts going through each piece, so you won't have to worry about the pieces rotating. and once you paint the parts black (assuming you're doing black) you won't even see the seam
