These galvanized steel flue grippers seem to work very well. I didn't have any trouble getting them installed and they really do grip tightly. My only reason for not giving it a full five stars is because they seem so basic that I felt they were overpriced. They way they work is that as you tighten then screws, the arms are splayed inside of the chimney pipe putting pressure on the cap frame and causing a tight fit.
