Overview

The Kupo KS705312P Baby 5-Inch Grip Arm Pin is a purpose-built mounting accessory designed for professional photography and video rigging. Measuring 5 inches in length with a standard 5/8" (16mm) baby pin, it inserts directly into grip heads, clamps, and other baby-pin receivers commonly found on lighting stands and grip equipment. The integrated 1/4"-20 and 3/8"-16 female threads on the pin body allow you to attach monitors, cameras, small fixtures, or other threaded accessories without needing separate adapters.

Constructed from steel, the KS705312P delivers the load-bearing reliability required on professional sets where gear safety is non-negotiable. The hex stud interface enables controlled tightening with a wrench, ensuring a secure and repeatable connection that holds firm through repositioning and transport. Its snap-in design supports rapid insertion and removal from grip heads, helping keep setups and teardowns efficient during fast-paced production days.
