And Wow to you for getting back to me so quickly! I did make a mistake on my measurement for the height where I had 1 3/8". It should have been 1 3/16".
As I understand it...there are three "dimples" on the side of the roller...two on the top and one on the bottom. I matched the 13/16" width by measuring the outside of the bottom dimple to the front edge of the roller and measuring the outside of the same dimple to the center of the wheel. Now, if the measurement is between the two top dimples, that measurement is 1 3/8". The wheel on my roller is 1 1/8". And no, I did not see the very last roller, 81-256...guess I gave up too quickly...thinking the padio door was too old!
Thanks for all of your help...I hope we can get things rolling.
