Abstract: A stanchion lock mechanism assembly is provided, including a clamp, and pin and a lever. The pin includes a first end and a second end, where the second end of the pin is engaged with the clamp. The lever is rotatable about the first end of the pin and includes a locked position and an unlocked position. The lever is selectively rotatable about an axis that is generally aligned with the pin when in the unlocked position. The lever rotates the pin about the axis, thereby advancing the pin and the clamp in a longitudinal direction with respect to the pin. The lever is rotated no more than one-hundred and eighty degrees about the axis between a first position and a second position, wherein the lever may be placed into the locked position.
