HARKEN 45 mm Aluminum Double Block — Swivel, Becket
Black Magic Air blocks are a top favorite of Big Boat performance racers and cruisers. These lightweight, free-running, powerful performers are used 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. Shackle blocks lock in two directions or swivel to keep line from twisting.
Key Features
- 30% lighter, 60% higher working load than equivalent sized ball bearing blocks
- Easy Maintenance — AirBlocks are easy to clean and service. Few parts and no loose balls or rollers to misplace. Fasteners allow quick disassembly with a single hex wrench
- Low Friction Caged Bearings — Roller bearings housed in unique center cage kept separated and parallel for lower friction. Dirt and sand falls out between the rollers
- Strong, lightweight sideplates and sheaves — 6061-T6 aluminum sideplates sculpted to remove excess weight. Thin-profile, deep groove aluminum sheaves have radiused edges to protect high-tech lines
- Long-lasting protective finish — Sheaves and sideplates are deep-saturation Hard Lube-anodized for strength and durability
- High- and low-load versions available
- Breaking load is 2 times safe working load
- Dissimilar metals isolated to prevent corrosion with plastic isolators under all fastener heads and headposts
- Three-way head — set screw locks shackle in front or side positions, or lets block swivel to keep line from twisting
