Use them anywhere: Core Blocks are a true all-around solution. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Universal Bearing: A tuned two-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high-dynamic or static loads.
