@jamest0o0 how big are the holes in your hardware cloth? I'm aiming to let as much sun light in as possible while preventing him from getting out. Is your hardware cloth metal?
Found this stuff, but the holes are a little smaller than Id like. The metal fencing has bigger holes with thinner...
They are XXR 527's, they are inexpensive wheels. You can buy them in matte bronze but the paint is garbage, it started pealing in less than a year. Bronze looks great on WRB cars.
I am thinking cement the front panel, back panel, and door. the pieces that connect the front and back (3 foot joint) will be un-cemented. Maybe I will use a bungie cord to hold these together just in case.
