SERIES 903
DOUBLE-ARM GATE

Series 903 is specially designed to control traffic for large vehicle driveways such as those found in truck terminals, airports or even military installations. The wishbone style arm is made of 2.54cm x 15.3cm clear, white pine extending 3.66m from the gate body. Further extension is made by a single board attached to the double arm by a galvanized bracket to allow total arm extension up to 18 ft. (5.49m). Galvanized steel brackets and zinc-plated fasteners achieve cross bracing. Arm assembly is counterbalanced with steel weights. All wood portions of the arm are painted with two coats of exterior black paint. Yellow warning stripes are applied diagonally to both sides of the gate arm for better visibility. An optional "light package" is available at an extra cost. Three warning lights with red lenses on both sides are installed on the barrier arm 1.2m apart with suitable gaskets for weatherproof installation. Operating voltage is 120V. A.C. This series has a synchronized double linkage drive assembly and is engineered to withstand the abuse of continuous operation.
Thermostatically controlled 500 watts heater ensures normal temperature in the cabinet during extreme weather conditions, preventing freezing of oil in the speed reducer and eliminating humidity on electrical components.
This gate can be fully automated.
