Sliding door roller
Thanks for reaching out! I'm sorry to hear that your purchase did not work out for you. There is a chance that we might be able to supply you with a replacement for your roller however, I'll need a bit more information to confirm.
To start, please provide the exact dimensions of your roller. Take a look at the diagrams below for reference for an idea of the measurements we'll need from you.
Thanks for confirming! The 9/16" measurement is only about 1/16" off from the 1/2" measurement you have. Theoretically, this roller should work in place of your existing roller.
If it will not fit in the door, I'm afraid that we do not have a replacement roller that would work in its place.
I do apologize that we cannot be of help with this repair.
Please feel free to reach out with any other questions you may have.
