Atrium Series 312 Sliding Glass Door Rollers

Thanks for posting. With rare exception, the only reliable way to identify sliding glass door rollers is to remove the old ones from the door to inspect them. There is too much variation otherwise, even when you know the brand. Atrium doors have sometimes been associated with our 81-030, 81-095, and 81-138, but I cannot say if any of these are what you need. Ultimately, you'll need to remove your old rollers and compare them with these rollers to see if they match up. If none of them seem right, please send me photos of your existing rollers, and also tell me the width and height of the assembly. I'll do my best to find something better for you. See the guides listed on this page.
