Patio Door Roller

Thanks for posting. Saunders Engineering Corp is no longer and business, but we may have substitutes that can work for you. I can't be entirely sure what you need without seeing pictures of the original roller, but start by looking at our 81-047. Double-check your dimensions to see if this matches your old hardware. If not, please send us pictures of your old roller assembly out of the door, and we'll see what we can find for you.
