Sliding door roller

Hi David,

Thanks for reaching out to us! We are not familiar with the roller you show in the photo, unfortunately. The roller looks pretty old so we aren't sure who manufactured it or if there are any direct replacements available. That said, take a look at the nylon wheel 81-236A and axle kit 81-310 to see if you could use them to complete your repairs. 

I've included a video tutorial below that explains the process for swapping out the rollers and axles.
