<p>These hanging stacking cones are designed to safely stack shipping containers and keep them in position while stacked. Lateral movement is eliminated when the cones are in place. While in use, containers are separated by the thickness of the flange. INSTRUCTIONS Lift container. While suspended, place hanging stacking cone into the underside of a bottom corner casting, cone facing down. Ensure it locks in place with the locking lever. Repeat for the remaining three bottom corner castings. With all four cones locked, lift the container to stack onto another container of the same size. Align the cones in the upper container with the corner casting holes of the lower container. Lower upper container until fully bearing on lower container. Ensure each corner of the upper container is fully seated on the cone flange. Your container is now securely stacked.</p>
