Harken 57 mm Black Magic, AirBlock High-Load Teardrop Cat. No. HAR 3223 Weight 1 lbs
3044 High-Load Teardrop Block-57MM
Teardrop blocks are
ideal for use as mastbase leads and for other
applications where limited articulation or direct attachment is
desired. When attached to an appropriate padeye, Teardrop blocks will
not hit the deck when lines are slack, yet allow sufficient movement to
ensure fair leads 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.
The 3042 and 3046 are
low-load blocks designed for use on production boats that have mounting
posts on the mastcollar.
