Strata-G Rings are longer lasting, more versatile matrix rings made from nitinol wire and Garrison Soft-Face. Nitinol drawn-wire nickel titanium is aligned at the molecular level for superior performance yet requires less effort to open. Garrison’s proprietary StrataSet™ treatment maximizes the longevity of this advanced material. The PEEK ultra-durable reinforcement on the back of the ring allows Strata-G™ to retain a higher percentage of initial strength for much longer than non-reinforced rings. Proprietary StrataBond™ silicone/PEEK tips withstand hundreds of applications. Includes: 1x SG400 (Short Ring) 1x SG500 (Tall Ring) 1x SG600 (Wide Prep Ring) Non-Latex
