Harken 57mm High Load Block with Becket – Black Magic Air (3216)
Durable, high-efficiency block for powerful multi-part systems
The Harken 57mm High Load Block with Becket (3216) from the Black Magic® Air series is built for big boat sailors who demand top performance from their rigging in heavy-load, high-action environments. Lightweight yet exceptionally strong, it’s ideal for mainsheet, halyard, runner, and spinnaker systems where consistent, low-friction operation is critical.
The integrated becket allows for clean terminations in multi-part tackles, making it particularly useful in cascade systems or where line routing space is limited. Inside, Torlon® roller bearings run on a precision centre cage that keeps them aligned and separated, reducing friction and maintaining efficiency under maximum load.
The block’s shackle head swivels freely or locks in two fixed positions, allowing riggers to adapt to changing lead angles while preventing line twist. Trusted by performance cruisers and offshore racers alike, the 3216 delivers reliable, free-running control in demanding conditions.
