A dual cam lock apparatus comprising a locking blade, a rotatable lock, a first cam and a second cam. The first cam comprises a first cam body and a first arm extending from the first cam body. The first cam is rotatable by the rotatable lock to move the first arm in and out of contact with the locking blade. The second cam comprises a second cam body with at least one slot therethrough which receives at least one protrusion of the first cam, and a second arm extending from the second cam body and coupled with the locking blade. The slot has an angular span across which the protrusion rotates before further rotation of the protrusion causes rotation of the second cam, whereby rotation of the second cam rotates the second arm to move the locking blade between the locking and release position.
