SmallRig 5399 5" Electric Suction Cup Mount Kit

SmallRig 5399 5" Electric Suction Cup Mount Kit – Rapid 100 ms Attachment with Continuous Pressure Monitoring

This all-in-one professional suction cup mount kit is built for vehicle shooting. It integrates an electric suction cup, a ball-head magic arm, and a safety tether into a single system. The kit combines automatic attachment, real-time seal monitoring, and multiple mounting interfaces so you can set up and shoot quickly.

Key features and how they help you shoot

The suction cup uses a high-performance motor that responds in under 100 milliseconds for rapid attachment, so you spend less time setting up and more time filming. A built-in pressure monitoring module continuously checks seal integrity. When pressure drops below 75%, the system automatically repressurizes to maintain adhesion.

Powered by a built-in 2000mAh battery, the suction cup supports QC fast charging (5V/2A via USB-C). It reaches a full charge in approximately 45 minutes and can provide up to 30 hours of continuous operation on a full charge. These power features let you run extended shoots without frequent recharging.

Durability, adhesion and operating conditions

The cup is constructed mainly from nitrile rubber. This material preserves sealing performance across a wide ambient temperature range, from -25°C to 60°C, and resists deformation in extreme conditions. Adhesion is strong: the mount supports vertical/side mounting up to 40 kg and horizontal mounting up to 60 kg.

For vehicle use, follow the included recommendations: pair the suction cup with the supplied safety tether, avoid loads exceeding 5 kg on the mounted equipment, keep vehicle speeds below 80 km/h, and avoid bumpy roads. Additionally, check the adhesion status every two hours during use.

Mounting base and compatibility

The aluminum alloy mounting base offers multiple interfaces for versatile setups. It includes anti-twist 1/4"-20 and 3/8"-16 threaded holes as well as 3/8"-16 ARRI locating holes. This array of interfaces lets you attach magic arms for action cameras or secure the safety tether for dynamic shooting configurations.

The kit also includes a protective dust cover to keep the suction cup clean and extend its service life when not in use.
