ABSTRACT:
The invention pertains to a synthetic plastic underground valve curb box assembly consisting of a vertically oriented casing adapted to enclose a buried valve wherein a base is associated with the curb box upon which the valve rests. The casing and base are locked together by "snap-on" connecting means wherein the casing may be pushed upon the base and automatically locks thereto by resiliently biased connectors, and the base permits a greater degree of valve support than previously attainable, the base being usable with both metal and plastic conduit valves.
