Hello,

Take a look at the 81-023 patio roller. I have used this part in the past to replace unavailable patio door rollers but it is a little tricky to install. Review the specifications shown on our product page to see if the roller housing will fit into your bottom door rail. Thank you. 

A professional from CA says:
81-023 is probably too wide.
Can you show us the end view of the roller and the frame rail it came out of?
The height and width are useful.
It looks similar to Bur-Val.

If the 81-023 does wind up being too wide, you could consider using something like the 1-1/4" diameter 81-224 wheel with the 81-304 replacement axle as long as your original housing is still in good condition and the wheel size matchs yours.
