Our gate has been in use for over five years. The only escape of the several dozen ferrets that have bee in there is a whippett, that got on top of the tent and flew over the top. The wall is a 3/4" sheet of plywood that is cut to be snug in the door frame, and is 18" tall. On top of it we have a 4+ inch diameter cardboard tube that we cut a groove down the length and fitted it over the top of the board. Our door easily keeps the ferrets in as they have nothing to grab onto as they try to escape, and slide back into the ferret room. The cardboard tubes can be gotten from a carpet or vinyl flooring store where they are thrown into the trash. The real cost to us was nothing as the wood was leftovers from another project. We really like the gate as it is so low, and is easy to step over. Harry C.
