Rollers for a sliding glass door

A quick learner from South florida says:

I'm looking for replacements for this sliding door roller. Best I could find was a patent number of "PAT. 3.670.357" and del mar engineering. Their website directed me to you guys. Appreciate any help you can provide.

Hello,

Your roller resembles our 81-112. It is a similar style but the dimensions will be the determining factor. Review the image from our product page below to determine if this could work for your repair. Thank you!
