Hello there. This looks a lot like the 81-158 Tandem Roller. The height is different from what you cite. Double-check your dimensions and see if this matches what you have.

Hi, my height is not like the picture above with a 1 inch height. Mine measures 1 1/4 in height. Everything else looks the same. I wonder if The top screw that secures the roller is the same dimension from the top down as mine. If so I might be able to adjust the rollers down that 1/4 inch difference. Do you know what that measurement is to the center of that screw to the top of the roller frame? It needs to be the same because the hole that is drilled in the side of the sliding glass door frame has to line up perfectly.

Actually, take a look at the 81-166S. I think this might be a closer match. See what you think.
