Sliding patio door rollers

A contractor from California says:
Hello Swisco, I was refereed by A and D glass to find this part from you guys. One of my clients does not want to replace the whole sliding door but fix it, so I am having hard time finding the part anywhere. Hopefully you have this part, will need 4 of them.

Thanks for contacting us. See our 81-139 roller to start out with. I'm afraid your exact roller is no longer available, but this may be a good alternative.
A professional from California says:
I can confirm. This an earlier model of the same door. I have used it and it works well.
A contractor from California says:
OK I will see if the client agrees with this product and give it a try. Thank you!!
