Yes. The Therm-A-Guards were installed on various sized bushings with top exit leads. The bushings and Therm-A-Guards were then subjected to sustained winds beginning at 50 MPH and continuing up to 125 MPH. The Therm-A-Guard latching system held the guards firmly in place (Wind loads above 125 MPH were not tested). Additionally with our open mesh design there is considerably less surface area for the wind to affect the bushing cover than with a solid wildlife protector.
