Abstract
A stanchion includes storage for a linkage member. The stanchion includes a hollow pole and a cap piece inserted into the top portion of the pole. Vertical movement of the cap piece may provide clearance for a linkage opening to allow the linkage member to be pulled from or pushed into the interior of the hollow pole.
