An improved telephone connector block construction permitting the convenience of blocks normally connected at parallel sidewalls thereof to be conveniently interconnected at a forwardly facing surface in those installations where side interconnection is not practical or desirable. The construction includes an element providing guiding means for jumper connections leading to the forwardly facing surface including the necessary fanning openings, and a second element forming pin terminal means on said forwardly facing surface. The improved structure permits the mounting of adjacent connector blocks at closer intervals than otherwise possible where specific installation sites require such closer spacing.
