Adjustable C Clamps on chain
This pair of nipple clamps is connected by 12″ of chain.
The 1″ long thumbscrews are fine-threaded for precise adjustment of pressure, and will not fall out even when the clamps are fully loosened.
The “grabbing” surface is approx ¾” long by ¼” wide.
This is good-old kinky ingenuity in cold hard metal.
The chain is easily removable with pliers if you so desire.
The weight of this item is approximately 55g.
