Kupo KS-022 Baby 5in Grip Arm Pin – 5" steel baby 5/8" pin with end collar to prevent slipping

This Kupo KS-022 Baby 5in Grip Arm Pin is a 5" (12.7cm) steel baby 5/8" (16mm) pin designed to mount in the head of a grip head or grip arm. You install the pin so that a few inches remain exposed, allowing a light fixture or any accessory with a baby receiver to be mounted directly on the pin.

What this pin does and how to use it

Mount the pin into the head of a grip head or grip arm. Once mounted, the exposed portion accepts fixtures and accessories that use a baby (5/8") receiver. The combination of a grip head and grip arm gives flexibility to position lights and accessories virtually anywhere on a set.

Additionally, the pin includes an end collar that prevents a mounted fixture or accessory from slipping through the grip head if the assembly ever loosens unexpectedly. This feature helps protect your gear and maintain secure positioning during use.
