Product Information
The SeaLife Flex-Connect 1" Ball Clamp (SL9907) is an accessory that joins two 1-inch diameter balls together so you can secure a light or strobe to a Sea Dragon camera and lighting setup. It uses spring-loaded aluminum plates for fast assembly and breakdown, a red anodized wing-nut handle for tightening, and weighs 2.1 oz./60g.
Who it is for
This clamp is built for underwater photographers and videographers running a SeaLife Sea Dragon lighting rig who want to expand or reconfigure their setup with grips, Flex Arms, trays, and other Flex-Connect accessories. Because assembly and breakdown take just seconds, it suits divers who need to adjust their light or strobe position between dives or dive environments.

Frequently Asked Questions
What size balls does the SeaLife Flex-Connect 1-inch Ball Clamp fit?
It fits 1-inch (25.4mm) diameter balls, letting you connect two Flex-Connect balls together, such as those found on the SL995 or SL999 Ball Joint Adapters or the SL9909 8" Ball Arm, to mount a light or strobe to your camera rig.
What comes in the box with the Flex-Connect 1-inch Ball Clamp?
The package includes one (1) Flex-Connect 1-inch Ball Clamp. It does not include additional ball arms or adapters, so you will need separate Flex-Connect components, such as the SL995, SL999, or SL9909, to build out a complete lighting arm.
Can the Flex-Connect 1-inch Ball Clamp be used with non-SeaLife mounting systems?
Yes. In addition to SeaLife's own Flex-Connect SL995 and SL999 Ball Joint Adapters and the SL9909 8" Ball Arm, the clamp works with other mounting systems that use standard 1-inch ball joints.
