The Mueller® Adjusta-Coil™ Meter Box is adjustable without added parts. The box is adjusted using the company's Thermal-Coil™ design. Installers set the box in place then twist its top, reposition it to the new grade level, then twist it again to permanently and securely set the adjustment. No more adjustment rings or shoveling are required. The boxes offer an adjustment range of 6" or 12", with a standard maximum depth of 60".
