Roller for my patio door

My name is Larry and I am having a hard time finding the part I know that it is no longer made so I need to know what the replacement part number is

Hi Larry,

We did carry this roller at one time but it has since been discontinued. In our experience, the 81-279 could work as a replacement. Keep in mind that the adjustment screw is a little higher and you may have to lift the edge of the door and angle the screwdriver up to reach the screw, but the wheel should roll smoother than the tank treads.

The 81-279 is on the thicker side, so you could also consider our 81-023 and see if the dimensions might work better for you. Thanks for posting!
