Telephone line splitter for dual devices

This iMBAPrice RJ11 T-adapter splits a single two-line telephone jack so two modular phones or a phone and an accessory can share the connection. The straight 4C modular design plugs directly into a standard wall jack without tools. A pack of two adapters is included for multiple locations.

Suits homes or offices adding a second handset

It works where a two-line jack already exists and the user wants to attach two devices to line one, line two or the combined pair. It does not suit installations that require an Ethernet connection or a splitter for data networks. Buyers needing to create new lines from a single-line jack should look elsewhere.

RJ11 4C modular interface

The adapter uses a male RJ11 plug and two female RJ11 ports wired for four conductors. This physical interface determines compatibility with standard analogue telephone wiring. Confirm the wall jack and devices use the same 4C modular format before purchase.
