Ring Opening Pliers - Larger-gauge captive rings are hard to insert and remove by hand, which is why we offer ring opening pliers for manipulating captive rings with ease. Choose from a variety of ring opening pliers made from quality, autoclavable materials like surgical stainless steel. You can purchase ring opening pliers individually in just the sizes you need, or buy one of our sets of ring pliers that work with captives in a variety of gauges. When using your ring opening pliers, be careful not to widen the gap too much. A small amount of pressure is usually all you need to remove the bead.
