Overview
The Kupo KS-425 Dia. 26mm Ball with 1/4"-20 Anti-Slip Screw is a professional modular mounting component designed for flexible positioning of cameras, monitors, lighting accessories, and rigging equipment in film production, television, photography, and studio environments.
Constructed from CNC-machined aluminium, the KS-425 features a 26 mm ball joint paired with a 1/4"-20 male threaded screw for direct mounting into compatible camera cages, plates, or accessories. The design is part of Kupo’s Super Knuckle ecosystem, allowing integration with other modular knuckle components for articulated support systems.
The unit includes an anti-slip rubber pad at the base, which helps prevent surface damage and increases friction for more stable mounting. A knurled tightening knob allows for quick hand adjustments, enabling fast repositioning during production workflows without the need for tools.
A built-in hex access point is also included, allowing additional tightening with an Allen key when extra security is required in more demanding setups.
