Sentinel's Eclipse product line is the revolutionary tower and catwalk solution for grain handling and equipment support that is specifically engineered for farm and other light-duty applications. Built to handle the harshest environments and most rigorous operating schedules, Eclipse towers use a roll-formed "C" channel design constructed from 12-gauge heavy-duty galvanized steel. The result is a comprehensive system that offers more strength, stability and safety than simple angle-iron products and is available at the same or lower cost.
