Just got a project done last night. We have a pocket door to the bathroom. It is stored back in the pocket when traveling. The weight of the door bouncing when traveling pulled the screws out of the ceiling. The only way to get to those screws is to cut out the back wall of a cabinet. This was my 3rd attempt at a fix. The first two times I tried to do minimally invasive surgery. This time we did open heart. Cut out the whole back wall of that cabinet. Made a trip to the hardware store (mask on) and found the proper screws so the rollers can clear the screw heads. Drilled all new holes and added a few extra screws. Should be good for a few more years.
