How to fix double pocket doors so they stays in the center when closed?
In our high end home the company I worked for built, we never got the converging kit. There was a block of hardwood carefully cut to full the gap in the track, slightly recessed so the cut block allowed the wheels to hit it. It's length was set so each side as it closes stooped just ever so slightly over the centerline of the opening, maybe a 1/16" or 1/32" to insure the doors met well. The block would be about 5-6" long though it could be shorter if warranted. The block was carefully centered and piloted for three screws to secure it in place. Stagger the screws as much as possible in the face of the block to help prevent splitting. Mask off and spray paint the track and block flat black and it all goes away.
