When buried service boxes must be replaced, the pipe on which they are housed is frequently damaged or rusted and must be rethreaded to allow for the installation of a new service box or coupling and extension. Service box threaders normally require a large hole be made around the service box connection so that the threader handle can be turned horizontally. This design for a service box threader, however, allows for use with only 3 in. (75 mm) of soil removed around the top of the pipe. this is especially significant when service boxes are in older subdivisions, sometimes buried below the grade under a driveway. The threader helps keep damage to such expensive‐to‐repair areas to a minimum.
