How do you remove the 84-020?

Hey there! Thanks for reaching out to us. The process of removing the 84-020 is fairly straightforward. You want to first remove the sliding door from the track and place it on a stable surface. Next, remove the two screws on the bottom of the door to release the roller. 

That's really all it takes. Once the old one is out, you can place the new roller into the door and reinstall the two screws, then put the door back up.

Please let us know if you had any a follow up question or ran into any further issues.
