Connect Aquatica's 6" DELTA 3 Double-Ball Stem Arm Section to a ball base mount on top of an Aquatica underwater housing's grip handle. Then, attach your DELTA 3 ball-mounted strobe arm to the other end of the stem arm segment. This setup extends your arm and adds another component to give you more flexibility. The recommended ball mount for the grip is Aquatica's #77657 Lower Section with T-Base. Two ball clamps will be required in order to attach the stem segment to the lower section and the strobe arm.
Each ball mount features an O-ring, which prevents slipping and enables a better hold with less force when the ball is connected to a clamp. Engineered to withstand the elements for many years, the arm is crafted from an aluminum alloy that's been hard-anodized for exceptional resistance to corrosion. It's also been treated with Teflon to make it even more durable, ensuring that it will survive the toughest aquatic environments.
