Back end of connector and inner dielectric flush. Center conductor is now in place.

3. Gently insert the center conductor down into the back end of the connector feeling it into the guide hole. When center conductor is not in place approx. 1/8" of center conductor will show.

4. Firmly push the cable home as far as possible, then screw the connector on the cable in a clockwise direction until it stops.
