AS an installer that has been around a bit. Stage side booms or pipe

need a strong attachment to the deck y\though should be secured at top
by a decently strong grid-to-pipe line.

Make sure the point at the grid can sup****t the weight should the
flange give way and enjoy...

You can use box truss to give the same and even protect the (CAST AND
DANCERS) by placing the instruments into the truss should you like but
be sure that over 10' of truss is also attached to the grid or viable
steel structure..
