2 Pack White RJ11 6P4C Female to Female Inline Coupler, Modular Telephone Cord Extension Jack Adapter

This 2-pack RJ11 inline coupler is a professional telephone wiring accessory with dual 6P4C female ports, designed to connect two separate telephone cords to extend cable length conveniently. It eliminates the trouble of replacing long telephone cables when the original line is insufficiently long.

With straight-through internal wiring and gold-plated terminals, it delivers stable signal for landline calls, fax transmission and DSL broadband internet, avoiding static noise and signal dropouts caused by poor contact. The smooth white casing fits well with home, office and hotel indoor decoration styles without messy visual clutter.

It works seamlessly with all standard RJ11 telephone equipment including desk phones, fax machines, DSL modems and wall telephone sockets. No complicated installation or external power supply required; just plug two telephone cords into both ends for instant connection.

Lightweight and durable structure occupies minimal space, ideal for household telephone layout adjustment, office fax wiring and DSL broadband cable extension projects.
