Set allows the neck to be firmly secured along with both wrists, if desired. A sturdy, comfortable heavy-duty collar wraps the neck, while two heavy-duty cuffs wrap each wrist with thick nylon straps that feature fully adjustable stainless steel lock rings, allowing for a controlled, custom fit. The professional-grade carabiners can support hardcore play and ensure complete control. Use the carabiners to link the cuff and collar set to other COMMAND products for optimum versatility.
