This roof mounted weathervane was handcrafted in alabama out of mild steel. The approximate measurements are: 18"h x 18"w x 13"d. It has been dipped in 2 coats of rust resistant paint so it may be enjoyed for many years to come. It comes complete with the top, nesw, and roof mount base. The base has 4 screw holes and can easily be bent to match the pitch of your roof, or fit around a post(screws are not included). It can also be bent flat if desired. This weathervane normally sells for $35+ in stores, so if youve ever thought about purchasing one for yourself or a friend, nows the time!!
