Description
Zircon blocks from Harken boast high performance due to the presence of industrial ceramic ball bearings that are securely mounted within caged races. These cages ensure that the bearings remain separated and do not come into contact with each other, resulting in excellent efficiency for small boat blocks. Zircon blocks are available in various sizes, including 40- and 57-mm sheaves, and in both single and double blocks, with or without beckets.
