Tandum slider door wheels.
Hello, thank you for posting,
We have a few similar roller assemblies to review the resemble your original. Please start by comparing the dimensions of the 81-030, 81-138 or 81-095 to see how they match up. The main dimensions to consider are the height and width of the housing along with the diameter of the wheel.
Let us know what you think and if you have any additional questions!
Thanks,
Chris.
With a 1-1/8" height on the housing, I would recommend the 81-030 instead. The housing is adjustable so you may be able to make up the difference in the wheel or if that does not work, switch out the wheel with the 81-223 1-1/8" wheel and 81-310 axle kit.
Another option to consider if the original housing is still in good shape, is switching out the wheel. Please review the video below and let me know if you have any additional questions!
