Roller parts

This sticker doesn't tell me anything about the door, unfortunately. To be honest, even with a manufacturer name there's a good chance that won't help you. Most doors use generic rollers. The only way to know what you have is to remove them from the door entirely.

I know that's more of a project than you had in mind, but that's just how these doors are designed. Anything less would just be guessing, even with brand names. I highly recommend that you consider removing the rollers from the door to ID.

If you decide to go that way, please show me a picture of the back end, side, and top. Dimensions would also be a huge help. From there, I'll see if anything in our catalog matches up.

This photo still doesn't show us the rollers but I think I can still help. What you have here is a Nu Air patio door. We carry two types of roller that they have been known to use: the 81-081 and 81-032B. You will need to remove your old roller to compare and determine the better match.
