It goes on a closet mirror door
Your roller looks like a good match for our 81-011 at first glance, but our dimensions do differ slightly. For example, I couldn't find anything as short as yours (1-1/16") with a 1-1/2" diameter wheel. You may want to triple check your dimensions just to confirm.

Hey there, maybe I can help.
To start, you mentioned that this roller is for a closest door. That's pretty strange right off the bat; I personally have only seen this type roller used on patio glass doors, exclusively. If this was on your mirror door then I think someone retrofit it during a past job.
That aside, the 81-011 Tom mentioned only comes with a 1" flat wheel. We also sell the 81-090 roller, but it has a 1-1/8" concave wheel. One possible solution is to use the housing and replace the wheel for something like our 81-236 nylon 1-1/2" replacement, along with the 81-310 axle kit.
