Key Features
- Superior Suction Power: Equipped with a 4.5-inch (115mm) rubber vacuum suction cup, providing horizontal suction force up to 60kg and vertical suction force up to 40kg. Recommended load-bearing for equipment in motion is 3kg.
- Multiple Interfaces & Compatibility: Features multiple 1/4" and 3/8" screw interfaces, supporting external accessories like magic arms. The top of the mount includes a 1/4" screw with ARRI telescopic positioning pins for secure attachment of various devices, including sports cameras (GoPro, DJI, Insta360), DSLRs, cell phones, and fill lights.
- 360° Universal Adjustment: The external magic arm utilizes a double ball head design, allowing for 360° rotational adjustment. A single adjustment latch facilitates easy changes to the shooting angle. ARRI positioning pins prevent device deflection for stable shooting.
- Easy Installation & Quick Release: The pump-activated suction cup attaches firmly by pressing the pump until the warning line disappears. To remove, gently pinch the two side tabs. The warning line provides a visual indicator of suction status, prompting re-pumping if exposed.
- Durable Construction: Made from high-quality aluminum for longevity and reliability. Includes a dust cover to protect the suction cup when not in use, maintaining its cleanliness and suction power.

Safety Guidelines
- Ensure the mounting surface is clean, smooth, flat, and non-porous before attachment.
- Press the pump repeatedly until the red warning line is no longer visible. This indicates a secure vacuum seal.
- Monitor the warning line during use; if exposed, repress the pump to enhance suction.
- It is recommended to check suction status every 4 hours to ensure solid adsorption.
- When used in motion (e.g., on a car), maintain a safe speed below 80 km/h (50 mph) to prevent accidental falls.
- Always remove attached equipment from the magic arm and suction cup before detaching the suction cup itself to avoid damage.
Setup and Installation
Attaching the Suction Cup
- Select a clean, smooth, and non-porous surface for mounting.
- Place the suction cup firmly on the chosen surface.
- Press the pump button repeatedly until the red warning line is no longer visible. This indicates a secure vacuum seal.

Operating Instructions
Adjusting the Angle
The magic arm features a double ball head design, allowing for 360° rotational adjustment. Use the quick lock knob to loosen, adjust, and then tighten the arm to secure your desired shooting angle. The ARRI positioning pin design helps prevent unwanted rotation and ensures stable shooting.

Removing the Suction Cup
- First, remove any attached equipment from the magic arm.
- Gently pinch the two side tabs of the suction cup where it says "OPEN" to release the vacuum seal. The warning line will reappear.
- Carefully lift the suction cup from the surface.

Maintenance
To ensure the longevity and optimal performance of your suction cup, always use the provided dust cover when not in use. This keeps the suction surface clean and free from debris, which can compromise suction power. Regularly inspect the rubber suction cup for any damage or wear. Clean the suction cup and mounting surface with a damp cloth and mild soap if necessary, ensuring both are completely dry before re-application.
Troubleshooting
Suction Loss
If the red warning line on the suction cup becomes visible during use, it indicates a loss of vacuum. Immediately repress the pump button until the warning line disappears again to re-establish a secure seal. Ensure the mounting surface is clean and free of dust, moisture, or irregularities that could prevent a proper seal.
Equipment Instability
If your equipment feels unstable or shifts, ensure all screw interfaces on the magic arm and the suction cup are tightened securely. The ARRI positioning pins help prevent rotation, so confirm they are properly engaged if applicable. Verify that the weight of your equipment does not exceed the recommended load capacity.
