2 Pack Cream RJ11 Duplex Wall Jack Splitter, 1 to 2 Dual Phone Line Modular Adapter for Landline, Fax Machine & Cordless Phone System

This RJ11 duplex wall jack adapter converts a single wall-mounted telephone socket into two independent modular ports, allowing you to connect two communication devices to one landline line without replacing wall panels.

Constructed with reliable internal conductive lines and shielding structure, it greatly reduces static and audio distortion during voice calls, fax transmission and ADSL network connection. The cream-colored shell matches most household and office wall decoration styles for a neat, tidy wiring look.

Pack of 2 splitters satisfies multi-room expansion and backup demands. The compact plug-in design directly attaches to standard RJ11 wall jacks, occupying minimal space and avoiding messy exposed cables.

No driver, power supply or professional installation needed. Simply plug it onto the wall socket, then link landline phones, cordless phone bases, fax machines or modems. It is an essential wiring accessory to solve insufficient telephone ports for families, offices and small business spaces.
