Got one to operate a small vent in a greenhouse. First one I ordered, the piston never worked. Returned and replaced with a second one, piston extended once about 75% and then after it closed, it never worked again. Temps in greenhouse have varied between 40 and 95. Not sure why. I've used the standard panel lifters with no problems. Guess is the springs might be too stiff for application but who knows. Threw original packaging away so eating the cost on this.
