US Tower MA Series Crankup Masts
The US Tower MA series crankup tubular towers are designed to be efficient and neighbor friendly, offering a clean, flagpole like appearance. These towers are self-supporting when used with the optional MAB and MARB hinged bases, also allowing the tower to be horizontally lowered. The MARB bases allow rotator mounting. The MA-40, MA-550, and MA-770 are supplied with a load actuated hand winch, flat base, two 1/2" x 10" anchor bolts, wall bracket, and top mounted rotor plate. All MDP models include a heavy duty motor drive with positive pull down instead of the hand winch. Positive pull down provides motorized raising and lowering of the tower, even in high wind situations where the hand winch will not always allow the tower to retract..
