Do I have the 81-280

A quick learner from Clifton Park, NY says:
I believe this looks to be the correct replacement part for my sliding glass door rollers. I am attaching a photo of mine for verification. I am a little concerned about the quality/life span of this roller given the small nylon roller pins. I have seen several fall out from my current rollers, so was just curious if you can think of another roller that could fit that may provide better performance/life span.

I appreciate any help you can provide,

I agree, the 81-280 looks to be our best match. Keep in mind that we have a limited supply. Due to its unique shape, we don't really have anything else that might work as a substitute.
