Abstract: An innovative and advantageous ratcheting system having a housing, a corresponding ratcheting member, and a primary ratcheting member. Wherein the members provide dependent interlocking behavior between the corresponding ratcheting member and the primary ratcheting member whereby the dependent interlocking behavior takes place on the adjoining surfaces orthogonal to the axis in which the ratcheting mechanism is rotatably mounted.
