This 5" Grip Pin (Old Style) from Kupo is a 5/8" (16 mm) steel baby pin designed to be inserted into a 2.5" grip head or arm, and leave a few inches out of the head for mounting lights or other gear with 5/8" receivers. The base of the pin is enlarged to prevent it from slipping through the head, while the top of the pin is rough textured to help you tighten down the light or accessory without it turning.
