Hi, I'm trying to identify the rollers on my patio doors. They do not have wheels like other types I've seen, rather small white plastic rollers. There is nothing on the doors to identify them but the hardware in my windows in the rest of the house appear to be made by "Sunrise". Any help appreciated. Thanks

Thanks for posting. 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 runs nicer than the noisy treads. Let us know what you think.
