You fix the rods under the roof frame of the boat lift, then pull the clear fishing wires over the end. Their effectiveness depends on factors like climate, attic size, and the existing ventilation system. Instead of displacing hot air (like internal fans tend to) whirlybirds expel this air from the building. Be cautious when handling tools and materials on the roof to avoid accidents. The whirlybird does not have a motor, but because of its special shape, its blades will still spin when it falls. Not only will your air conditioning system be more efficient, but it will also improve roof ventilation, and prevent damp, stale air.
