How do I know what rollers I need?

Question

I have a sliding door and I'm pretty sure it's from 1982 when my condolences was built.  The patio door is small, like apartment size, because I have a condo.   How do I know which rollers I need.  It jumps off and I have to lift it and adjust to get it to close without sticking.  Thank you for any help you can give.

There's only one way to identify patio door rollers, and that's to remove them ahead of time. This kind of project requires removing the door twice, at minimum: once to identify, and again to replace. You'll need to set time aside one afternoon and grab an extra pair of hands to help you. This is not a simple fix you can do in a few minutes.

When the roller is out, measure the outer housing and write down what you get for us to review. Please also take clear photos of the back end, side, and top. We can then check our inventory for a replacement.
