Buffalo box in [Cambridge, Massachusetts](/source/Cambridge%2C_Massachusetts)

A **curb box** (also known as a **valve box**, **buffalo box**, **b-box**, or in British English **stopcock chamber**) is a vertical cast iron sleeve, accessible from the public way, housing the shut-off [valve](/source/Valve) (curb cock or curb stop) for a property's water service line.[1][2][3] It is typically located between a building and the district's [water main](/source/Water_main) lines and usually consists of a metal tube with a removable or sliding lid, allowing access to the turn-key within.[4] It typically serves as the point denoting the separation of utility-maintained and privately maintained water facilities.

The name *buffalo box,* the first word often capitalized, is applied to curb boxes because they originated in [Buffalo, New York](/source/Buffalo%2C_New_York).[5]
