Roller for unidentified door

I'm afraid your roller was discontinued, but we might be able to help. Take a look at our 81-279 and 81-023 as a possible substitute. The adjustment screw on the 81-279 is a little higher (I had to lift the edge of the door and angle the screwdriver up to reach the screw), but the wheel rolls nicer than the tank treads. I can't make any guarantees, but look these over and see what you think.
