Overview
The Kupo KS-033 Grip Arm Pin is a professional 5" (12.7 cm) 5/8" baby pin designed for use in grip heads and grip arms within film production, television, theatre, photography studios, and broadcast environments. It is a core component used to mount lighting fixtures and accessories onto articulated grip systems, enabling precise positioning and flexible rigging setups on set.
Manufactured from chrome-plated steel, the KS-033 is built for durability and reliable load handling in demanding production environments. The 5/8" (16 mm) spigot is designed to fit standard grip heads, while the integrated length allows for secure extension and positioning of lights, modifiers, or accessories.
The pin includes both 1/4"-20 and 3/8"-16 threaded sockets, providing additional mounting flexibility for accessories. A knurled neck section improves friction inside grip heads, reducing slippage during adjustments. The built-in collar acts as a safety stop, preventing the pin from sliding through the grip head if loosened during use.
This makes the KS-033 a fundamental grip accessory for building flexible lighting rigs, especially where precise control over fixture placement is required.
