I need a new set of rollers for a pella sliding door. It is an older wood/aluminum clad model with blinds between the glass. I want to be sure I'm ordering the right rollers. I have attached a few photos of the roller and door to help identify. There are no visible model or serial numbers on the door. Thanks.
