The "Y" series anchors are one of the most frequently used anchor systems, mostly for their reasonable prices. The anchor arms may be corrugated to improve the transition effect. The "Y" series anchors are used for light to heavy refractory concretes and are suitable for fast arc welding. They are normally corrugated on the open section of the arms, but may also be corrugated along the entire length. The type and length of corrugation should be specified when ordering.
