Bought a second hand Hormann canopy garage door to replace my old door. The Hormann came prehung on a wooden frame, which I have successfully bolted to the brickwork in garage.
The frame is square to the brickwork, but you can see from the picture, the door doesnt appear to be square inside the frame, resulting it catching on one side when it closes. My question is how do straighten the door inside the frame ?
