A vertically extending clevis pin is adapted to slide within the apertures of the vertically spaced apart plates between an extended position and a retracted position. The pin further includes a pin housing having a guide slot, wherein the guide slot has an offset portion used to lock the pin in either the extended position or the retracted position. Further, the pin houses an internal spring having a torsional bias that urges the pin to a locked position in either the extended or retracted position.
