The Marwell Corporation K7 to 9s Adapter will allow the retro fit of a Landis & Gyr K7 meter socket to a 9s socket style meter. This adapter is a direct “bolt in” application without any modification to the meter socket. The “K7-2-9s” adapter will allow the Utility to convert the service to a CT rated installation without the interruption of service to the customer. The “K7-2-9s” is equipped with LED bypass circuit which are activated automatically when the meter is removed, so a test switch is not required.
