Hi - This is from an Andersen "Terratone" (I think that's the right name) sliding glass door from the mid-1980s. I'm pretty certain it's the original roller. 7163-2 is stamped in the top. (See Photo). Thanks

Hello,

Take a look and compare our 81-128 roller to yours, which are used for Andersen Perma-Shield Gliding patio doors that date back to 1982 and are still used today. Thanks for posting!
