Pantry Won't Stay on Top Rail

[ellenov]

Has anyone with a pantry in their Thor motorhome had a problem with the top rail of the pantry slider door staying on the rail? It only has one top rail instead of two so it jumps off as soon as you put any weight in the pantry.

I haven't had a problem with mine jumping the rail but I would love to know how to remove or disengage the bottom slide so I can remove the pantry to add some screws to the top rail.
