Universal modular jack assembly, 4 or 6-conductor, with ivory plastic face plate. Can be utilized to mount a wall telephone or as a flush mounted wall jack for use with desk telephones. Includes two screw type slotted posts, which are required when the unit is used to mount a wall telephone, and two plastic hole plugs when used as a flush jack. Also furnished are screws for attaching the unit to a standard outlet box. Each unit is equipped with an insulation piercing terminal block and quick connect wire retaining clips which hold the conductors in place.
