Rollers from a 23 year old sliding glass patio door

A home owner from Eugene, OR says:

I need four of these so my two sliding glass doors can open and close easily. I'm doing this parts search at the direction of the contractor who is also replacing a broken pane in one of the doors.

According to the contractor, these doors were made by Insulate Industries which is now owned by Ply Gem

These sliding door rollers wheels are nylon and have a wheel diameter of 1 1/4". I can find a nearly identical part but with 1 1/2 inch steel wheels.

Thanks for posting! I've seen this roller before. Unfortunately, we don't have an exact match, but a previous customer of ours actually got the 81-158 to work as a substitute. The 81-087 is also a possibility, depending on your roller's dimensions. You can see more information here. Let me know what you think!
