81-183 rollers

Thanks for reaching out to us. I'm not too sure what to suggest for the rollers as it isn't possible for us to identify them when they're still installed. Yours might just be a single wheel with no adjustment. You might need to contact a carpenter or a professional who is familiar with installing these types of rollers in your doors. I am very sorry for any inconvenience. 

Thank you for the additional photos. Our 81-018 looks like it could be a match for your old roller but note that we always recommend sticking with the original hardware the door was designed to use as a policy. You're welcome to see if you can adapt the 81-183 to your door but we cannot guarantee it will work. Our return policy can be found here just in case.
