I had situation where I needed the 558 Ball Stud to attach a Light Can to a floor stand. The origanl clamp on the Can had a squeeze clamp which made it impossible to attach to the stand. Adorama had the Smith Victor Studs. The 558 Ball Stud does the job perfectly. Adorama had to back order one (I ordered 3)but I was impressed that they kept me informed as to when I would get the 3rd one. Good Job.
