We have two of these doors in our house. I took the working roller off the good door the bad door roller wheels are completely broken and falling off the axle. Glass etching on the door is PPG Herkulite K ANSIZ ? 971-1966 3/16 inch U.
We need to rollers if there is a match out there.

Hello,
Take a look and compare the specifications of the 81-018 to your roller assembly. Thanks for posting!
