I'm afraid I cannot confirm what roller you have. You are only showing the inside portion. There should be an outer housing, perhaps still in the door. Would you be able to show us the complete roller unit?
Thanks for the reply.
I don't have access to the door (it's my mother and father's home) but I think you are right. The second still functional roller assembly was impossible to get out, probably due to the housing still being attached. This one just slid out the bottom. I now know that I would have had to really disassemble the entire door frame to get the functional one out.
Any guess as to the model given the dimensions?
Is there such a thing as universal one that would work on most doors?
Thanks again,
