Rothco's Thin Red Line Silicone Ring is ideal for fire fighting professionals looking to prevent finger injuries caused from wearing a metal ring. The ring is made of a medical grade silicone that is non-conductive which provides a safe, durable alternative to the traditional metal wedding ring. With a tensile strength of 80kgf, this silicone ring is meant to stand up to extreme pressure when put to the test. The Thin Red Line center shows respect and support for Fire Fighters.
