Abstract: Abstract of the Disclosure The suspendable locker has a plurality of side walls and a top wall interconnected to define an interior space. The suspendable locker has an open bottom leaving the interior space exposed from below. A door is hingedly connected to a side wall to provide an access opening into the interior space along a side at the bottom so a cart can be rolled into and from the interior space. An attachment structure for suspending the locker from a storage cabinet is connected to a side wall. The attachment structure includes a pair of L-shaped flanges connected to an exterior surface of a side wall. The L-shaped flanges engage a lip on a tool storage cabinet, enabling the suspendable locker to be cantilevered from the storage cabinet.
