Thanks Jerry. We got some off-Forum feedback also and are convinced the best practice would be at least one support per piece, so are thinking max spacing should be 21'-0". The feedback was from a contractor who does grain elevators with VERY tall risers and they use half-lengths with a support on each piece!

If it's not a multistory, just 1 hanger ring at the top of the riser within 24" -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Brad Casterline Sent: Friday, June 13, 2014 9:52 AM To: [email protected] Subject: Support of tall risers Where "seismic" is not required, and the riser is, say, 6" by 35 feet tall, is there a requirement or rule of thumb for the vertical spacing for the support of it?
