Patio door rollers

Hi there, thanks for reaching out to us. While your old wheel with tread isn't made anymore, we have something you can use as a substitute. Although it looks quite different, our 81-279 should make for a good solution. Let me know if you have any questions or reservations. 

Good. I  still want to go with our 81-279 as a recommendation. Look it over if you have not done so already and see if this will work for you. As for a screw, see if you can go with either our 33-013 or 33-104.
