SLIDER BALL - a sliding lock of the round form - is intended for mobile fixation of several wires in a row during winding of coils.
I have nothing to do with it, but I was looking for and selecting, and eventually this model is one of the best, since the clamp initially has the planes we need, and not as usual the hemisphere. The edges of the pressing planes have small bends that push the wire towards the center.
Excellent quality of plastic and springs!
Color ONLY black.
