Convert your 2-line phone jack into a triple configuration. Add any 2-line device in line 1, 2, or 3 ports on the jack. Additionally, you can use our 15' or 25' Phone Power Cord Extension for added length and a Single Line Extension Cord.
Note: Most homes are wired for 1 or 2-line service. For 3 lines, the home or office must be wired with 6 conductors or 8 conductors for 4 lines.
