Sliding Door Roller Help

A landlord from Lisle, IL where patio doors are says:
October 16, 2021

This condo was built in approx. 1965 and we believe these doors are original. Approx. 8 ft. metal patio doors that meet in the middle with two stationary doors at either end. Extremely expensive to replace and no one knows who the manufacturer is.

The right hand door has been used forever and just about fell apart yesterday. Handyman put back together temporarily and back on track. Can you identify from 4 pics taken? Your site is terrific and if compatible pieces can replace broken parts, will be ordering asap.

I will take more pics later today for other replacement parts.

Thanks for being there for those of us hanging in with originals

Hello! I unfortunately don't know who made your door either, but the roller in question looks an awful lot like our 81-027. It has the same dimples on the sides and everything. Review our dimensions and let me know if they match up, or if you had any other questions!
