Sliding door roller
Hello,
I don't recognize this roller at first glance but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. Thank you!
I don't believe your roller is still available but take a look at the 81-050 and 81-084 to see if these will fit your door. Secondly, take a look at the 81-258 and 81-258S rollers to see if you could use just the inside part of the roller and fit it into your existing housing.
Lastly, take a look at the roller and axle kit 81-266 and see if you could get away with just replacing the wheel. Also, look over the related videos that we think you'll find helpful with this repair. Thanks for posting!
