ACORN glass sliding patio door

A home owner from CT says:

I have a Acorn manufactured 8'x81" glass sliding door. It does like slide well at all. The track seems to be fine. Wondering if it might be the roller and what model of roller it may be?

Yes, the roller just may be the culprit. I'm not sure what you have exactly, though. Our 81-030 is made for Acorn doors, but I cannot guarantee this will work for you. You will have to remove your existing roller and carefully compare it to the specs we show for it. If they don't match up, you can take a few pictures of your hardware and upload it here for us to see, and we can work on finding something better. Thanks!

Hi Tom,

Thanks for your reply. I might have to change the whole door, giving that my glass is all fogged up. Do you carry Acorn patio door?

I'm afraid we don't! If the glass is fogged, I recommend contacting a local glass shop, they may be able to help.
