Abstract: A transit positioning device for use with a conventional manhole mount having an elongate vertical arm and an elongate horizontal arm orthogonally joined together at a joint. A transit holding platform is rotatably mounted to an end of an adjustable length elongate member which in turn is mounted to the horizontal arm of the manhole mount. Further, an adjustable length stabilizing arm is provided with one end hingedly connected to the vertical arm below the joint at a position spaced apart from the joint, and a second end hingedly connected to the horizontal arm at a position spaced apart from the joint.
