RJ9/RJ10/RJ22 to RJ11 converters. Easily switch between RJ11 & RJ9/RJ10/RJ22 plugs with these adaptors. RJ9/RJ10/RJ22 4P4C to RJ11 6P4C converters. Note RJ12 (6P6C) plugs WILL fit these adaptors but they are only 4 way so the outer two pins of the RJ12 will NOT be connected! These converters are straight wired, if you require a custom pin out please contact us.
