Abstract
A pre-stressed concrete storage apparatus includes a plurality of panels secured together to form a hollow interior space for storing items. An outer door panel is selectively moveable for restricting access to the interior of the apparatus. A secondary metal door and cage assembly is located behind the primary outer door panel for further restricting access to the interior of the storage apparatus. A pulley system is provided for mechanically lifting and lowering the outer door panel.
