Your EZ Vane Bison Weathervane will be a welcome sight as you return home from wild adventures… and simple shopping trips. Bison have always been respected for their wild, freedom-loving nature and their ability to adapt, endure, and persevere. Wind cups spin on smooth ball bearings for excellent performance in all conditions. Directional markers are also included. Choose a deck mount, post mount, garden stake, or four-way mounting bracket for the peak of a roof. Strong steel is coated in scratch-resistant zinc and copper coatings plus a clear UV-protectant.
