The Harken Zircon blocks are the most efficient blocks on the market due to their industrial ceramic ball bearings that are mounted in a caged race. The cages keep the bearings separated so they don’t bunch, touch, and stop each other resulting in the most efficient small boat block Harken has ever made
Sheave Ø - 29mm
Length - 43mm
Weight - 10.5g
Maximum line Ø - 6mm
Maximum working load - 80kg
Breaking load - 240kg
