iMBAPrice RJ11 4P4C Inline Coupler 15 Pack

Inline coupler for RJ11 phone lines

This pack contains fifteen straight modular inline couplers designed to join two RJ11 telephone cables together. Each unit provides a female-to-female RJ11 connection that extends the reach of existing phone cords. The couplers suit home or office installations where a single cable run falls short.

Female-to-female RJ11 connectors in bulk

Every coupler accepts standard RJ11 plugs on both ends, allowing a simple push-fit connection without tools or soldering. The straight-through wiring maintains the original pin-out across the joint. Buying the fifteen-pack keeps spares on hand for multiple rooms, workstations or future rewiring jobs.

Passive design needs no power or cooling

Because the couplers contain no active electronics, they draw zero power and generate no heat or noise during use. Signal quality depends on the cables attached, not on the coupler itself. Users who need powered signal amplification or digital data rates beyond analogue voice will require different equipment.
