'bout 30 ft if I recall, 15 ft for the crown of each tree. You biggest problem with having larger than individual cages is going to be the little bucks getting in there and rubbing the trees. They seem to ABSOLUTELY LOVE rubbing on fruit trees. It must be the scent they get off the bark or something, but we left ONE tree unprotected when we wrapped the others because we ran out of daylight, and the next morning, sure as shrite, the thing was rubbed.
