In the 2010 the requirements for lateral bracing were found in 9.3.5.3. The section I quoted, 9.3.5.5.10 should reference 9.3.5.5 in the 2013, and it was not updated in the code cycle. It should be noted that the above is my opinion as a member of the NFPA Automatic Sprinkler System Hanging and Bracing accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the NFPA or its Committees *Ken Wagoner, SET *Parsley Consulting*** *350 West 9th Avenue, Suite 206 *Escondido, CA 92025-5053 *****Phone 760.745.6181* Visit our website <http://www.parsleyconsulting.com/> *** On 7/22/2014 12:26 PM, Brad Casterline wrote: > Ken, > > Is the section you reference 13-2013?
