The Kupo KS-074 127mm Long Double Stud Baby Pin for grip head is designed to be mounted into a grip head, or grip arm and still have a few inches sticking out of the head where a light fixture or any other accessory with a baby receiver can be mounted. The combination of a grip head and grip arm give you complete freedom to position your light fixtures or any accessory with a baby receiver virtually anywhere. Having a couple of these babies in your grip kit will give you unlimited possibilities.
