Design and Build

The KS-474 uses a die-cast aluminum alloy shell together with matching ball heads and a metal knob to deliver a reliable yet lightweight assembly. The 26mm ball heads receive a hard anodized treatment and a serrated surface. Consequently, the ball heads engage the shell more securely and offer improved resistance to weathering. In addition, the shell’s two deeper side cuttings increase the possible tilt-down angle, giving you more positional flexibility when mounting gear.

Functionality and Use Cases

Because the KS-474 features double sockets and ball heads, you can interchange components to configure mounts for different devices. For example, use it to position lights, mount cameras, attach monitors, or support tablets and smartphones. The central knob locks both ball heads and the arm in place, so you can set the angle and tension quickly and reliably.

Dimensions and Capacity

The knuckle’s overall length measures 151mm (5.95”), while each ball base measures 3” (77.8mm). The socket-to-socket length is 2.32” (59mm). The unit supports a loading capacity of up to 8 kg, making it suitable for a variety of small to medium accessories used in filmmaking and related fields.
