Anybody used a top on these to keep the climbers in?
On my 10x10 outside kennel, I ran a treated 4x4x10 across the top of the front, then attached it with pipe clamps. Then I took a 2x4x10 across the top of the back, and attached it with clamps. I then attached R-Panel sheets to the wood. I have a 10' span, there is not any bowing, the water drains fine, it created shade, and the dogs cannot climb out. This setup survived Hurricane Ike, so I am gonna say the design it worked...
