[Sprinklerforum] Re: 1" Armover Restraint

Tim is correct, and I caution those on this forum not to confuse "bracing" with "restraint" as -13 clearly identifies them as two different approaches.  From the '16, §9.3.6.1 identifies restraint as a lesser degree of resisting loads.  This is repeated in the '22 in §18.6.1. It's important

Also in section 9.2.3.7 Sprigs. Sprigs 4 ft (1.2 m) or longer shall be restrained against lateral movement. At one time it was only required in seismic areas but since 2013 it is required on any sprigs 4' or longer, as I understand it. Thanks Brett Peters General Manager Installation & Design

George, An arm over to a single sprinkler is defined as an arm over whereas when two sprinklers are served, it’s considered a branch line. Branch lines require restraint. If the arm over is to a sprig up longer that 4ft, the sprig requires restraint. I am not aware of a requirement to restrain
