I was going to use 45 degree couplers to make peaks, and then down to the ground and attach to the kennel panels.
What size pvc? I used a 1-1/4 for the run. My original thought was to do the same, but due to the width, it wasn't stable using the 1-1/4(would have needed lots of support). Then I thought, going to a smaller pvc, but I'm not sure that would be strong enough. I did leave the tops open, so I can add. They are about 5 ft apart and then I would have to go 8 ft n from each directions(that is where I lose stability)
