Bases for rooftop mounting of equipment can be custom manu-factured to precise specifications, says the company. Each base is custom built due to the varying specifications of rooftop units and roof configurations. Delivery is usually within two weeks after receipt of the order, the company says. Options include a built-in roof pitch, extra height for installation of sound traps beneath the unit, and a pressure treated wood nailer. Bases are all welded construction and are shipped in one piece if trucking permits, says the manufacturer.
