Attach a lighting arm to your underwater housing and tray system with this 1.0" Delta 3 Ball Mount to Flat Plate from Aquatica's Technical Lighting Control series. It features a standard 1.0" ball mount with an O-ring, allowing for connection to optional arm components via ball-joint clamps. The O-ring prevents slipping and enables a better hold with less force when the ball is connected to a ball clamp.
At the other end of the unit is a flat plate for attachment to housings, trays, or grips with 5mm holes, which are standard on many systems using metric threads. The required mounting screws and a hexagonal wrench are included. Built to last, the ball mount is made from aluminum that has been hard anodized and treated with Teflon for resistance to corrosion and other wear and tear.
