Black Magic Loop Blocks
Soft attachment Loop blocks
are now available in the Harken® Big Boat Black Magic® block line.
Standard on America’s Cup and Grand Prix yachts, lightweight soft
attachments are the structural component that carries the primary load,
and as a result the block is lighter weight because it uses less material.
Sophisticated engineering prevents the block from capsizing during
intermittent loading.
Roller bearing Loop blocks are
highly efficient and are used where constant adjustment is required, such
as sheets, halyards, running backstays, and control lines. Soft
attachments fasten to padeyes and other support structures without
splicing.
Torlon® roller bearings are
housed in a self-contained center cage to keep them parallel for
low-friction efficiency and easy maintenance. UV-resistant Delrin® ball
bearings carry thrust loads. |
