That's a good question. Some say yes despite having a diameter smaller than 1" because they are a fitting. Our position has been that they are ok for retrofits but if a new job and one cut the drop too short, cut a new drop. I believe there is a Public Input on these since some are combining 2 or 3 extensions. We'll see.
