The Ring Lock ™ A-Frame series is designed to deliver ultimate strength and power. The guides of this series are unique in their kind in terms of durability and functionality they offer. Their skeleton is ATLAS 316SS ™, the strongest stainless steel frame. The height of the loop and the horizontal support, type A, prevent the driver from turning and loosing the ring. The angular fold at the base prevents the loop from collapsing and the small foot support does not affect the blank behavior. Their ring is hollow circumferentially to minimize the friction of the yarn or line. Additionally, it almost surrounds the entire surface of the ceramic in order to avoid any loss. Their ceramic is Duralite ™ and consists of an improved material with a high content of aluminum oxide, making it lighter and stronger.
