Can't remove sliding glass door
Can't lift the sliding glass door out of the frame because the header has sagged about 3/8" over the years. The sliding glass door unit is 94" wide and the slider is 48" wide. I have tried moving the door to either end of the track and the side of the door that is on the end of the track, barely clears the track but the other side, which is in the center of the track, will not come out. Top of the door is right against the top track.
I was thinking of using a hydraulic jack to lift the center of the header enough so I can remove the slider and replace the rollers.
Any other ideas?
