I have a large glass sliding door that has a broken roller. 2 of us carefully removed the door and checked our the rollers. One must be replaced.
It has only one roller, not two.
The size is 1 1/4" wide by 2 1/4 long.
I don't think the length matters, and the width is standard at 1 1/4".
Due to the size and weight of the door, I am inclined to get the double roller.
Is that OK?
