SmallRig 5" Electric Suction Cup Mount Support Kit 5399

The SmallRig 5" Electric Suction Cup Mount Support Kit 5399 is a smart, all-in-one mounting solution designed for vehicle shooting, action cameras, and creative hobby video setups. It combines automatic suction, real-time pressure monitoring, and multiple mounting interfaces in one compact system, making it a practical choice for dynamic filming on smooth surfaces.

The kit includes a 5-inch electric suction cup, a magic arm with ball head, and a safety tether, giving you a reliable setup for capturing stable shots from cars and other flat, non-porous surfaces.

• Fast electric suction system with motor response in under 100 ms
• Real-time pressure monitoring with automatic pressure boost when suction drops below 75%
• Built-in 2000 mAh battery with USB-C QC fast charging (5V/2A)
• Up to 30 hours of runtime on a full charge
• Full recharge in approximately 45 minutes
• Strong holding power: up to 40 kg / 88 lb on vertical or side mounting, and up to 60 kg / 132 lb on horizontal mounting
• Durable nitrile rubber construction designed to maintain a tight seal in temperatures from -25°C to 60°C
• Aluminum alloy base with versatile mounting points for accessories and camera rigs

Built for versatility, the aluminum alloy mounting base features 1/4"-20 threaded holes, 3/8"-16 anti-twist threaded holes, and ARRI 3/8"-16 locating holes. This gives you more freedom to mount accessories, attach a magic arm, or secure the included safety tether for more demanding shooting scenarios.

A dust cover is also included to help protect the suction cup and extend its service life.

Lab tests with vertical/side mounting and a 7" arm showed a maximum load of 5 kg / 11 lb under ideal conditions. Actual performance may vary depending on the surface, environment, and usage method.

Key Safety Notes

• Use only on clean, dry, smooth, and flat surfaces.
• Avoid rough, wet, uneven, fragile, or porous surfaces.
• Keep the suction base and foam filter clean and undamaged.
• Use extra caution on surfaces covered with protective films.
• Recommended operating temperature: -25°C to 60°C (-13°F to 140°F).
• For vehicle filming, use the included safety tether, avoid loads above 5 kg / 11 lb, do not exceed 80 km/h / 50 mph, and avoid rough roads.
• Check suction performance regularly, at least every 2 hours during use.
