The 2" XT-5FT-TRBR Round Support Bar from ProX is designed to mount on top of a 1 3/8" spigot-equipped stand and to support your lights or accessories. The bar is 1.5 Meters 5 foot (59.5") long, allowing enough room for four focusing ellipsoid or par lights or even a pair of speakers when used on a stand of adequate support capacity. Utilization of heavy-duty 2" clamps will increase the stability of your fixtures. Speakers should always be mounted from factory fly points and all equipment on the stand/crossbar should always have safety cables attached.
