Line Jack Unit: 1 x BT431A BT socket

These products contain an integral IDC snap down block with the colour codes of the wires printed on top, which makes them easy to wire and re-wire without the need for an IDC tool. They have been designed to accept CW1308 telephone cable (round, solid conductor, 2 pair, 4-core). They are particularly useful when installing a fixed-point telephone extension socket for equipment such as digital satellite receivers, computer modems etc, or for making up specific length extension leads.
