This Aquatica TLC Arm Set gives you complete lighting control since it is made up of two 11" double 1" ball middle sections. The included flat plate with 1" ball can be screwed directly into the handle of an Aquatica or other manufacturer's housing.
You need to attach a ball head adapter for a specific strobe with the included ball clamp. The ball head adapter allows adjustment of the strobe without having to move the arm set.
