assembly on either side of the telephone wire and
press the halves together very lightly. As shown

edge of the board for the IC473A models. Now
press the halves of the assembly together firmly. (If
at this point it becomes clear that your cable is too
thin or too thick to be used with this strain relief,
call Black Box Technical Support.)
