Hello,

I would recommend starting by comparing the specifications of the 81-261 to your roller assembly. The determining factor would be how the housing height, width, and wheel diameter compare to yours. We'll include the dimensions from our product page below. Thank you!

Thank you for the direction. We will check the dimensions but I thought I would ask about the screws. Our mounting screw is the bottom one and the height is adjusted with the top screw. Would that help narrowing down the roller? Thanks again.

We did carry a roller similar to yours at one time, unfortunately, it was discontinued. Our records show the 81-020 as another possible replacement but the dimensions would be the determining factor. Also, please note that you would need to reverse the installation and adjustment holes on your door to install one of our replacements. If you decide to give either option a try and run into any issues, our return policy can be found here
