I'm trying to get a part number for this "pivot capped track guide" that needs to be replaced from a 1990's vintage Stanley Monarch mirrored glass bifold door. I will need 4 of them but only one is seriously worn out. Or is there a replacement upgrade?
Thank you for your help.

Hello! This looks like a match for our 21-174 roll guide, which is a fairly common sight on many different bifold door tracks. Look it over and see what you think.

Is this wheel available? I need 4.

We still sell the 21-174, yes. All orders can be placed directly on our site at your convenience.
