Sliding glass door roller

Thanks for writing in! The 81-157 Tandem Patio Roller is not an exact replacement match for your roller but it is pretty similar in design. Carefully look over the diagram below, double check the dimensions to determine if this could be a fit for your door. 

The wheels on this roller are 1-1/4" in diameter but this roller should still work, providing the other measurements are a match. You should be able to adjust the housing in the door to accommodate for the difference in the diameter measurement.
