Very easy to install and does the job of keeping pigeons out from under the solar panel. There is plenty of mounting hardware. Some of the discs I had to push on the tile to make tight before I put the rod through, not that big a deal.
I used this around the base of an 8 x 16 chicken coup along the bottom. It was cut straight unlike some others I have used . It is stiff enough to keep straight but not so stiff you couldn’t work with it .
