The present disclosure provides an advantageous underground enclosure/assembly for housing electrical components. More particularly, the present disclosure provides an underground enclosure/assembly (e.g., handhole/pullbox assembly) that is configured to protect wiring connections and provide access to those connections for initial installation, and later for maintenance/alteration. The present disclosure provides for a cylindrical body and a frame with a lip feature to interface with the cylindrical body to enhance the durability and to assist in maintaining the circularity of the cylindrical body. The advantageous frame provides for a feature (e.g., a notch) to integrate fill materials with the frame. The frame further includes features for interfacing a cover.
