During operation of an illustrative, non-limiting embodiment of this invention, the automatic release hook does not need to be manually manipulated to release a suspended, attached, or coupled item. When a load is suspended or hung from the hook, the counter-weighted locking arm maintains the release hook in a locked or secured position because of the weight of the load. When the load is placed on a surface and the weight of the load is no longer carried by the automatic release hook, the counter-weighted locking arm pivots and releases the release hook, which, in turn, releases the load.
