We are suspending a speaker system in a gym. The tubing will span across 2 roof trusses and be bolted in place at each end. The speakers will be suspended using a "fly bar" that attaches to the speakers which is load rated by the speaker manufacture. The roof trusses should be more than enough...

Will 3"od X .250" wall ASTM A500 Grade B square tubing safely carry a single point load of 180lbs. over a 12ft span. Thanks
