DSA has also been trying to require all drops over 4 ft. to be restrained. Seems they think a drop is no different than a sprig. Go figure. Jason

Sprigs are a separate category independent from risers. That alone would not convince many folks that have an excessively literal mind. Fortunately, we can then ask, if a 4-way brace is required why would 13 state: Sprigs greater than 4 ft shall be restrained? This issue come to our attention when looking at riser nipples. That's why we now have the 3 ft allowance. Beyond that, if it's feeding more than one sprinkler, I think you have to treat it like any other riser.
