Ulanzi CO78 Super Clamp Magic Arm Kit: Your Desktop Studio Solution
Imagine having the ability to mount your phone, camera, or light anywhere – on your desk edge, a shelf, a tripod leg, or even a pole. That is exactly what the Ulanzi CO78 Super Clamp with Magic Arm Kit offers. This all-in-one mounting solution eliminates the frustration of juggling multiple accessories by providing everything you need in one complete package.
The CO78 kit combines three essential tools: a heavy-duty super clamp, a flexible two-section magic arm, and a phone clamp. This thoughtful combination means you can start using it immediately without purchasing additional parts. Whether you are setting up a live streaming studio, filming overhead cooking tutorials, or creating professional product reviews, this versatile kit adapts to your needs.
What makes the CO78 particularly special is its innovative 3-jaw Y-shaped clamping design. Unlike standard two-jaw clamps that can wobble or slip, this three-point contact system provides superior grip and stability. The clamp opens wide enough to grip flat surfaces up to 33.5mm thick and round tubes up to 45mm in diameter, making it compatible with desks, shelves, light stands, tripod legs, handlebars, and various other mounting points.
