Carbo Airblocks > 40 mm Carbo AirBlocks

Use the 40 mm Black Magic Carbo Air Block for jib and mainsheet systems on hi-performance dinghies. For the ultimate system , use Technora, Dyneerna, Kevlar, or Spectra line with the cover stripped where it runs through the blocks: however, the 40C will take line up to ³/₈''(10mm). These blocks are also ideal for highly-loaded control lines on small keelboats.

The double and triple swivel blocks can lock in two directions or swivel.
