The TUL-1000 Ball Mount from TUSA attaches to the TUSA TUL-1000 Underwater LED Light. Its 1" ball joint enables connection to optional lighting arms, and its other end attaches via the supplied screw to a small mount with a plastic D-ring at one end. This ring is designed to allow for the attachment of a lanyard or other accessory. The light then connects to the top of this small mount. All necessary hardware is included. The ball mount is constructed from aluminum with stainless steel hardware and has a rubber O-ring.
