MK Logic Plus K422 WHI: The Professional Master Connection
The MK Electric K422 WHI is designed to be the first point of entry for your telephone service. Unlike “secondary” or “slave” sockets, the Master Socket contains the necessary circuitry—including a bell-ringing capacitor and surge arrestor—to protect your equipment and ensure your service provider’s signals are correctly terminated.
As part of the Logic Plus series, it features a sophisticated, slimline design with a chamfered top edge. It is manufactured from a high-grade thermoset material that is naturally antimicrobial, making it a safer choice for homes, offices, and healthcare facilities.
