Roller replacement

A home owner from TN says:
Trying to find the roller replacement part for my old (circa 60's) glass sliding door. Can't seem to find online anywhere, anything that looks similar. No part number or item information is on the roller piece itself. Only "Ador" markings brand on main door.

We carry a few rollers that have been used on Ador sliding glass doors, such as the 81-258, 81-258S, 81-179 and 81-123, but all these look different from your old part. It may be too old to have a replacement. Compare the dimensions of your old hardware to these rollers to see if any might work for you.
