Kupo KS-419 Ball Head For Convi Clamp & Cheese Plate

Kupo KS-419 Ball Head for Convi Clamp & Cheese Plate – Double Socket Arm for Ultra‑Versatile Mounting

The Kupo KS-419 is a super knuckle that combines a double socket arm and a 26mm ball head at each end. You lock both ball heads with a single centre knob to achieve precise positioning. It provides a compact and flexible solution for mounting and positioning small cameras, monitors and other accessories.

Key features

• Double socket arm with a ball head at each end, locked by the centre knob for secure positioning.
• Standard Dia. 26mm ball heads with hard anodized, serrated surfaces for better grip and weather resistance.
• Die-cast aluminum alloy shell and CNC-machined aluminum ball head for a balance of strength and light weight.
• Shell designed with two deeper side cuttings to allow a greater tilt-down angle.
• Built-in silicon rubber sleeve holds the unit together while you change the ball head.
• Interchangeable double sockets and ball heads let you combine components for many setups.

Construction and handling

The KS-419 uses a die-cast aluminum alloy shell together with CNC-machined aluminum ball heads and a central knob. This construction makes the knuckle sturdy yet light. The ball heads feature a hard anodized, serrated finish so the shell can grab the ball heads firmly and resist weathering. Additionally, a silicon rubber sleeve is built into the unit to hold components together while you change ball heads, simplifying adjustments and maintenance.

Compatibility and mounting options

The round plate on the KS-419 has holes and is specifically designed to mount on the Super Convi clamp using the supplied M5 screws. You can also attach it to standard cheese plates using either two 3/8” bolts and nuts or two 1/4-20” bolts and nuts. The mounting holes are spaced 1” center-to-center to allow easy connection within a super knuckle system.

Suitable uses

The double sockets and interchangeable ball heads provide a wide range of application options. Use the KS-419 for lighting setups, camera mounting, attaching monitors, or positioning tablets, smart phones and other mobile devices. Its design supports creative rigging where flexible angles and compact assemblies are required.
