rollers for sliding door

Hey there, thanks for posting. I'm very familiar with this old "tank tread" roller. It hasn't been made in a long time and you won't find an exact match anywhere that I know of. The good news is that we've had a lot of success using 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 and it should work even better, despite the many differences in design. Look it over and see what you think.
