Electromechanical Masts

Product Description
These are telescopic, operated by a single screw and have multiple stages automatically locked / unlocked as the mast is extended / retracted. The advantage of these masts are that they are rugged in spite of being light, self locking at all stages for extended periods, besides being simple to operate and maintain. These are being used extensively by defence forces and we are supplying our masts with unique stage lock patented design for greater reliability of operations and free from maintenance.
