A leveraging tool for helping urge open a shipping container or van trailer door latch has a shaft that has a pair of rings that receive a latch arm of the door latch and uses the lever action of the shaft to gain mechanical advantage in opening and closing the latch. The shaft is bent at either one location or optionally two locations to allow for proper clearance of a user's hands with respect to the door. The inner ring has a distal end facing outer edge that is diagonally tapered to allow the device to properly clear the latch in order to allow the rings to receive the latch.
