Extended voice cable

The Monoprice 939 is a 2.1336 metre flat telephone patch cable fitted with RJ12 6P6C male connectors at both ends. It replaces shorter cords on landline handsets, wall sockets or inline couplers where extra reach is needed. The reverse wiring flips the pin order inside each connector, so installers must verify the target device expects this layout.

Capacity and headroom

Six conductors carry standard voice signals across the full 2.1336 metre run without signal degradation. The flat silver-satin jacket routes cleanly along baseboards or under carpet, yet the cable offers no shielding for data-grade applications such as DSL or Ethernet. Buyers needing longer runs or higher-frequency bandwidth should select a different cable type.

Bundled accessories

No adapters, splitters or mounting hardware are included with the 939. The only addition is Monoprice's lifetime warranty coverage on the cable itself, which provides a replacement path if a manufacturing fault appears. Software, drivers or configuration utilities are not supplied because the product is a passive copper assembly.

Questions about this item

Will the 2.1336 m Monoprice 939 RJ12 reverse cable reach from my wall jack to the desk phone without stretching?

At 2.1336 metres it provides roughly seven feet of flat silver satin cable, enough for most desk-to-jack runs while keeping the reverse pin order required by many voice systems.

How can I confirm the reverse wiring is correct once the 939 cable is plugged in?

Plug both RJ12 6P6C ends in; the handset should dial and ring normally because the reverse cable swaps the right-to-left pin order inside each connector for voice-line compatibility.

Does the Monoprice 939 package include any adapters or only the cable itself?

The box contains the single 2.1336 m flat six-conductor RJ12 male-to-male cable; no couplers, splitters or line filters are included.
