Hello, I was wondering if you could help identify the rollers on this old vinyl patio door, I have not been able to find anything similar. I'm sorry I do not have them removed from the door.

Hello,

Unfortunately, these old 'tank tread' rollers are no longer made. However, we've had people successfully use the 81-279 as a replacement. The adjustment screw sits a little higher than on your old roller but the wheel rides better than the noisy treads. Take a look and let us know what you think.
