10 pieces → 25 pieces →Marine Grade 316L stainless steel split rings, 1.25 inch (32mm) outside diameter, 2mm wire. The large, heavy-gauge ring for full key sets, tool tags and equipment tagging.
- Highly corrosion resistant. 316L exhibits high resistance to corrosion and oxidation, and will withstand a multitude of washings with detergent, household chemicals and salt water.
- Rust resistant around water. Boat lockers, dock lines, wash bays and outdoor gear — 316L holds up to salt and moisture far better than ordinary 304 stainless.
- 2mm wire. A stiffer ring that resists splaying under weight.
- Opens with a thumbnail, closes flush. Evenly wound so keys slide on cleanly and stay put.
- Solid stainless throughout. No plating to chip or wear away.
