1980's 36 inch sliding glass door with one fixed side and one sliding side

Question

Hello! This post is for my mother in law. She took her sliding glass door apart and is having a hard time finding any brandage or model or part numbers.

The wheel diameter is 1.125"
The housing height is 1.125"
The housing length is 2.125"
The housing width is 9/16" without dimples, and 12/16" with the dimples

Thanks so much and any questions please let me know!!!

We are looking at part number 81-229 and just want to verify this is correct! Thanks!!!

Hello! I agree, our 81-229 looks like the best option. All of our dimensions match up precisely, with the sole exception of the length. Fortunately, length isn't a critical measurement and you can get away with this minor difference.
