Harken 75mm Aluminum Loop Block — Wide
Black Magic Air blocks are a top favorite of Big Boat performance racers and cruisers. These lightweight, free-running, powerful performers are engineered for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems. A center cage keeps Torlon® roller bearings separated and parallel to reduce friction, ensuring smooth operation and optimal load distribution. Shackle blocks lock in two directions or swivel to keep line from twisting, providing exceptional reliability and precision for large sailing applications. The wide model is designed to accommodate lines up to 14 mm with a maximum working load of 2268 kg (5000 lb) and a breaking load of 4536 kg (10000 lb).
