Neptune round shower door
I have a 2007 Holiday Rambler Neptune with the round shower door that used to be a real problem jumping off the rails and out of the enclosure. I took the door out of the motor home and remounted the rollers. On all four rollers I moved them about an 1/8 of an inch closer toward the glass and about 1/4 inch toward the middle of the door. So far remounting the rollers has solved the problem but I still use a small bungee cord to secure the door to the top of the frame just in case.
