The Herm Sprenger Ultra Plus Prong Training Collar is chrome plated and available in four sizes. The addition of the center plate connector allows the middle link to be configured symmetrically, so they tighten in the same direction. This design improves the effectiveness of the training collar. Additonal links may be pruchased to lengthen the collar.
