End Booms are available in several lengths (3′, 13′, 23′, 32′, 42′, 51′, 61′, 85′ and 105′). Truss rods and inverted truss supports provide the primary support for strength and stability. The 6″ sand trap and control box, for the optional booster pump, are located near the tower for ease of servicing. The booster pump itself is located at the end gun for maximum efficiency.
