HARKEN 3234 

Single Black Magic® Footblock AirBlock® - 75mm  NEW!

The entire line of Black Magic® AirBlocks® has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same.

Used on offshore boats, these strong, lightweight blocks feature high-load Torlon® roller bearings for a high strength-to-weight ratio and reduced wear. Rollers are housed in a center cage and stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum side plates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion. Like all Black Magic® AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.

Use for:
  • Sheets
  • Halyards
  • Running backstays
  • Control lines

Specifications:
  • Sheave Diameter - 75mm (2-15/16")
  • Max Line Diameter - 9/16" (14mm)
