A below ground meter box for a fluid meter includes a first sleeve for placement at the bottom of a pit in which the fluid meter is located, the first sleeve having apertures for receiving fluid conduits for the fluid meter and a second sleeve of greater axial length than the first sleeve but of substantially the same diameter; the upper edge of the first sleeve has internally an abutment edge spaced a small distance therefrom and externally a curved wall section extending above the upper edge so that when the second sleeve engages the upper edge of the first sleeve, the curved wall section will prevent lateral movement between the sleeves.
