Replacement roller

Thanks for reaching out to us. I'm sorry to say that the only way you're going to know which roller is best for your door is to remove the original and compare it to the dimensions and photos we show on our site. I know that this is more work than you wanted to put into this project; removing a patio door without having a replacement on hand is a big ask, but it is a necessary and routine step for this kind of project. You should expecting having to take this door down twice at minimum: once to ID the roller, and again to replace it.

To answer your question more directly, these rollers are used on a variety of different door manufacturers. Even in cases where they're specific, it's always a good idea to check just in case. You never know when your door might be the exception to the rule. The people who install these doors make all kinds of last second adjustments, changes, and full alterations before the project is finished. Speaking from experience, it's better to be safe than sorry. You should check the original before you buy anything.
