I'm afraid that code doesn't tell us what you have. You likely won't find a number on your door that tells you exactly what roller is currently installed. Most door manufacturers don't design their doors with roller replacement in mind, and would rather you replace the entire door. They don't want to make it easy for you. We can help you find a match, but we will need to see a picture of the roller removed from the door. Comparing physical details, such as design and size, is the only way to identify hardware like a patio glass door roller.
