Patio door rollers

Hello there. It's tough to say without actually seeing the roller out of the door, but I believe you have an old discontinued roller that is not made anymore. With that being said, we've been told by professionals in the past that the 81-279 works well as a replacement. The adjustment screw is a little higher but the wheel rolls nicer than the noisy old tank tread style. Review the specifications below and let us know if you have any other questions.
