Abstract: A tool for closing a shipping container door comprises a head with two extensions curving away from the head and having a space between them sufficient to accommodate a bar bracket of a locking bar on a shipping container door. The head also has a handle that can function as a lever, so that when the tool engages the locking bar about the bar bracket, an operator can close and secure the shipping container door. Optionally, the tool also includes other components, such as features to engage other mechanisms useful in shipping, such as locking bars for opening shipping container doors, and twist locks for coupling and uncoupling shipping containers.
