SeaLife Flex-Connect 8″/20cm Rigid Ball

SeaLife Flex-Connect 8″ Rigid Ball Arm (SL9909)

The SeaLife Flex-Connect 8″ (20cm) Rigid Ball Arm (SL9909) is the ideal solution for divers and underwater photographers who need a solid and reliable way to mount and position heavier photo or video lighting equipment. Designed for maximum stability, this rigid aluminum arm ensures your lights stay securely in place even in strong currents or when precise light direction is required.

Crafted from black anodized aluminum, the arm offers exceptional strength, corrosion resistance, and durability, making it perfect for repeated use in both saltwater and freshwater environments. Its rigid design provides steady control and minimizes unwanted movement, allowing you to maintain perfect lighting angles for sharp, professional underwater shots.

When paired with the Flex-Connect Ball Clamp (SL9907), sold separately, the 8″ Rigid Ball Arm becomes part of a versatile and expandable lighting system. It also works seamlessly with the Ball Joint Adapters (SL995 & SL999), which are included in the SeaLife Flex-Connect Ball Arm Kit (SLKIT11). Together, these components create a 15.5″ (40cm) arm extension that provides excellent reach and flexibility for any lighting setup. For even greater reach, simply add a second Ball Arm to gain an additional 9.5″ (24cm) of length, ideal for wide-angle configurations or multiple light sources.

Like all SeaLife Flex-Connect components, the Rigid Ball Arm integrates easily into your existing setup, offering a modular system that grows with your needs. Whether you’re capturing macro close-ups, reef scenes, or deep wreck dives, this arm delivers the strength, precision, and adaptability needed to achieve professional results.
