Big Boat Blocks

Strong, Lightweight and Free Rolling
Weekend cruiser? Around-the-world racer? You’ll want Black Magic® AirBlocks® aboard. With high strength-to-weight ratios and free-rolling, high-load roller bearings, these versatile blocks are the workhorses of the Harken® line. Use for sail controls that see lots of action including mainsheet, runner, halyard, and spinnaker systems. AirBlocks® are very easy to clean and service. They have few parts and no loose balls or
rollers to misplace. Unlike blocks that are riveted together, three fasteners allow quick disassembly for service.


Details Make the Difference
LOW-FRICTION CAGED BEARINGS
The center cage keeps Torlon® roller bearings separated and parallel to reduce friction. Dirt and salt falls between rollers. Captive Delrin® balls carry sideloads.
STRONG, LIGHTWEIGHT SIDEPLATES & SHEAVES
6061-T6 aluminum sideplates CNC sculpted to remove excess weight. Thin-profile, deep-groove aluminum sheaves have radiused edges to protect high-tech line.
LONG-LASTING PROTECTIVE FINISH
Sheaves and sideplates are deep-saturation Hardkote-anodized for strength and durability, and UV-stabilized with black additive for maximum protection. Teflon®-impregnated for a smooth, slippery surface.


1. Isolated Metals
Dissimilar metals isolated to preventcorrosion: plastic isolators under all fastener heads and headposts. T hree-Way Head Set screw in three-way head locks shackle in front or side positions, or lets block swivel to keep line from twisting.
2. Easy Maintenance
AirBlocks® are designed for easy maintenance. Three fasteners allow quick disassembly using an Allen wrench. Blocks have few parts, and there are no loose balls or rollers.
