We were hired to do a 3 camera video shoot plus sound and lights for a debutant ball being held in a tent measuring 120' x 60'. We could not have any cables on the floor. Here's how we did the lights. <table cellpadding="0" cellspacing="0" border="0"> <tr><td colspan="2"></td></tr> <tr valign="top"><td></td> <td></td></tr> </table> The second and third pictures were repeated on the other tent poles We had our machine shop create custom brackets to attach our fixtures and truss to the tent poles. The picture below shows a bracket with a single rigging point. This was used to hang the truss from chain since tent poles can move or sway due to wind and can not be hard connected. The picture also shows the same bracket with a pair of 2" O clamps attached, these were used with a 2' piece of steel pipe to attach fixtures to the other four tent poles.
