Closet Door Roller for a Country Coach RV

Question

This is a roller for a closet door in a motor home. It is supposed to have a threaded post on the top to fit through the bottom of the closet door to secure it and adjust the door.

This looks to be the inside portion of a roller unit. Could you show me a picture of the outer housing? It should still be installed in the door. Seeing the whole roller unit in one picture would be a huge help.
