Arch Base

Extension type curb box with arch pattern base-for 1/2" through 2" curb valves

The arched base rests on top of the valve and extends down around the valve head to help exclude dirt and debris. The box is cast iron and is furnished with a cast iron lid and brass pentagon plug (the H-10314 is furnished with a one piece lid that requires a spanner wrench to remove – wrench ordered separately). The upper part of the box is spring loaded and telescopes into the base to allow for grade adjustment within the range given in the dimension charts. Stationery rods, shut-off rods, and pentagon keys are optional and are ordered separately.
