• 2 female RJ-11 / 1 female RJ-14 (4 wires)

See all images showing front and back of each splitter, individual wrapper showing how two are wrapped.

Important Notes (PLEASE READ): 

These splitters are designed to split two separate phone lines available in one wire (2 or more pairs), into two single-line RJ-11 phone jacks.   These splitters are not for the purpose of splitting a single phone line into two jacks.   e.g. not suitable to connect call blockers (or any device) in parallel.

These splitters can be used to connect 2 call blockers (one on each line) to a 2-line phone that has a L1/L2 Socket on the base.
