The Bondage Ring Barrel Clamps provide you with the framework for a wide array of torments. These heavy-duty clamps feature a dangling ring at their base that affords you countless bondage options. Let the rings hang and jingle as your sub moves around. Attach a chain from one ring to another that will swing with their movements and provide a slight tug, or a set of hanging weights for even more of a pull. The rings are perfect for attaching independent ropes or chains to create any nipple torture setup that you can imagine. The clamps are highly adjustable via their threaded barrels – no forgiving spring-loaded clamps here! Just screw them down tight for unrelenting pressure! Their rubber-coated tips keep your lover from having to remember their safe word (at least for now!). Measurements: 4.57 inch overall length (including rings), 1.12 inch inner diameter ring pulls, 0.55 inch diameter barrels Material: Coated Brass, Rubber Color: Black and Silver Note: Price is for one pair
