ABSTRACT:
An improved underground box and lid for use in irrigation systems and other underground systems is provided. A single box can be inverted, combined and interlocked with a second box to form a single enclosed structure that is twice as high. This can be used for those installations where underground system components are buried in the ground at a greater depth than can be accommodated by a single box.
