SERIES 230 SUN AND SHADE ROOM FOUR SEASONS

Hey Judy. Unfortunately we can't cross-reference this information to a specific roller. With rare exception, this is usually the case with sliding glass door rollers--the parts are often generic and thus can't be identified by brand, and therefore the only reliable way to ID what you have is to remove the existing rollers and send us good photos. Measurements, including the width and thickness of the assembly and the wheel diameter, is also useful to know. It would be best if your handyperson could do this for you, if necessary--we'll then do our best to ID the replacements you need. The videos below detail how to remove and replace patio door rollers, as well as how to identify the right replacement. Take a look. 

Thank you! These photos are a huge help. My top recommendation is our 81-154. I feel fairly confident that this is what you want, but your next step should be to carefully examine our dimensions to verify that they all line up with the original. As long as they do then you should be good to go!

You're very welcome, Judy. Please feel free to reach out if we can be of more help.
