The weight of the tripod is 535 lbs, and the speakers weigh approximately 50 lbs per pair. The approximate installation dimensions are depicted in Figure 1. The maximum height of the lowest speakers is limited to 60 feet above the ground. The tripod was evaluated for wind speeds of 100, 130, 150, and 200 mph.

The pressure on the roof values are due to the total weight of the system and ballast, as well as the downward reaction due to wind loading. Verification of the adequacy of the roof structure needs to take place before installation. Installations are for roof surfaces with enough friction; metal-to-metal or metal-to-wood installations are prohibited.
