About this product
The Harken 57mm Aluminum Low Load Black Magic Block with Swivel is a high-performance choice for mainsheet, runner, halyard, and spinnaker systems. Designed for both racing and cruising applications, these blocks feature a center cage that keeps Torlon roller bearings separated and parallel to minimize friction and ensure smooth, free-running operation. The swivel head allows for versatile rigging, preventing line twist, and can be locked in two directions.
