Abstract

The present embodiments generally describe a monolithic, e.g., integral, box unit and methods of manufacturing monolithic box units. The monolithic box unit has a ring portion and a body portion, both of which are molded and set simultaneously. The method proceeds with filling a female oriented cavity with a Polymer mixture, allowing both the ring portion and body portion to fill and cure at the same time. Once ejected from the cavity, the entire unit can be trimmed and then add hardware and cover to complete the box.
