The Mueller® Thermal-Coil® Meter Box provides a means to allow a meter to be read and maintained even though it is set deep in the ground to resist freezing. The Thermal-Coil Meter Box is designed with the meter installed on a platform that normally sets near the bottom of the box where the ground temperature keeps it warmer. The meter and platform are connected to the service line by coils of polybutylene tubing which allow the meter and platform to be raised to the surface.
