I built 25 hangars, would not even consider a hydraulic 1 piece door until I was convinced to try a Powerlift.  Ordered it , next thing I knew it arrived with the installers,  looked great painted matching color, very Good workmanship. Installed in 4 hours everything fit and worked perfectly.  Would recommend this Powerlift to anyone. Installed on 60×60 Morton in KROS
