Repairing Sliding Doors
Last month we took a 5300 mile trip to visit the National Parks in the Moab, Utah and Northern Arizona area. The Interstates were brutal, I-70 outbound and I-40 back. The routine when we stopped for the night was level the trailer, open the door and rehang the sliding door for the bathroom and the bedroom. Of course this damaged the doors. One of the wheeled travelers bent and another broke. On the four brackets screwed to the top of the doors the catch that is supposed to lock in place bent and the solid portion of the top of the doors split. Fortunately a local RV dealer had the replacement trollies and brackets.
The splitting of the doors where the screws went in was the easy part. I drilled out the screw holes and glued in 3/8" diameter oak dowels. This solved the splitting and provided solid wood for the new longer screws.
I took solid oak and made a filler that fits under the door. In this I used large head alan bolts screwing into threaded inserts.
Now as part of the leaving check list I close the doors, unscrew the alan bolts two turns so the door is lifted up slightly taking the load off the trollies and top of the door then the door is returned to the open position and secured.
When we get to our destination the procedure is reversed and the doors slide as always.
