Patio Glass door roller 1" height and 1/2 inch width Metal 1" roller

I'm afraid I don't know what it is you have. In order to assist you, I will need a photo of the roller in question. Please make sure it is fully removed from the door and visible without obstruction. I will specifically need to see it from the top, sides, and rear. Thank you!

Thank you. The design of your roller is very close to our 81-090. The dimensions also line up almost perfectly, though your height is listed as 1" while ours is 1-1/32". You may want to double check that just to be safe. The length also differs, but that's fine. Length doesn't really matter that much. I think your roller is just an older version of this part. Look it over and see what you think.
