Stacking Cones

Stacking cones are container lashing devices that fit perfectly into the holes at the corners of containers.
They are specially made to align stacked containers on a ship and prevent them from falling. However, they do not lock containers together. To make sure the containers don’t fall due to extremely bad weather or other causes, a double stacking cone can be placed that aligns the containers horizontally.
Stacking cones are mostly used in the hold of a vessel. They are available with and without a flange. OSHA compliant models are available as well.

Twistlocks

Twistlocks are conical automated devices, used to secure containers when transported on a ship.
They have a rotating mechanism that goes into each corner casting of the containers. In contrast to stacking cones, they do not only align containers, but they also can be used to lock them together.
Twistlocks are mostly used on a deck of a vessel. There are 2 types: the standard intermediate twistlock with a handle and the semi-automatic twistlock (SATL).
