The entire line of Black Magic® AirBlocks® offers a sleek look to match its unique, performance-packed engineering. These strong, lightweight blocks feature free-rolling, high-load Torlon® roller bearings for a high strength-to-weight ratio.
Teardrop blocks are ideal as masthead leads and in other applications where limited articulation or direct attachment is desired. When attached to a compatible padeye, teardrop blocks will not hit the deck when lines are slack, but allow enough movement to ensure fairleads when jumping halyards. They are often used on permanent backstays of fractionally rigged boats where the backstay can be spliced directly to the head of the block.
