Build on your underwater lighting setup with this 11" Delta 3 Double-Ball Arm Segment from Aquatica's Technical Lighting Control series. Using a ball-joint clamp, which is also available from Aquatica's TLC line, you can attach one end of it to a grip handle or stem equipped with a ball mount on top. A second clamp will allow you to connect the other end of the arm segment to your strobe or an additional segment. Each ball measures 1" in diameter.

The arm and mounts are constructed from aluminum that has been hard anodized and treated with Teflon for resistance to corrosion and other wear and tear. Each mount features an O-ring that prevents slipping in order to enable a better hold with less force in the clamps. Slots along the length of the arm segment allow for connecting accessories.
