Do these happen to be on your site as: Patio Sliding Glass Door Roller, 1-1/2" Dia.
81-039 ?

Thanks for writing in. The 81-039 is certainly possible, but the only way to know for sure is to go over the dimensions below. Compare them with your old roller and see if they match. Alternate image for 81-039
