The S-Biner NanoLock is the small solution to your split ring struggles. Measuring just over an inch tall and nearly ½ inch wide, this miniature stainless steel carabiner allows you to clip, carry, and change keys with ease. Simply clip a key, fob, or key accessory to one of the dual spring gates, clipping the other to a keychain. Once clipped, there it will stay—NanoLock features a narrow opening and novel gate design that ensure a key won’t accidentally slip off unnoticed. And when it’s time to remove a key for a walk with the dog, tune-up with the mechanic, or keychain upgrade, simply push the spring gate for instant, effortless detachment.
