Patio door rollers

Thanks for posting. I am afraid I can't cross-reference Simonton to a specific roller. With rare exception, this hardware tends to vary even when you know the manufacturer. The most reliable way to know what roller you need is to remove an existing one and send us pictures. The width and height of the entire assembly, as well as the wheel diameter, is also crucial to know. We'll do our best to narrow down what you need from there. See the video below that details how to remove and replace sliding glass door rollers.
