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 the arm over (but if it’s long enough….) I’m sitting in an airport without a book so there might be other opinions Bob Caputo On Thu, Oct 19, 2023 at 11:35 AM George Medina Jr. <[email protected]<mailto:[email protected]>> wrote: I have an armover that is 2'-4" in length. The SEOR is requiring me to put a diagonal brace on the branch line that the armover is supplied from and a restraint on the armover ( I had left a branchline restraint detail from my template and I probably should not have left it on with these small aromovers) When is an armover required to be restrained (if at all?).
