Harken HK2654 Quad Carbo Air Block 40 mm for Rope 10 mm
The Harken HK2654 Quad Carbo Air Block is designed for ropes up to 10 mm in diameter. This advanced block is 60% stronger and 30% lighter than classic blocks, offering superior performance while reducing weight.
Ideal for use in jib and mainsheet systems on high-performance dinghies, as well as control lines on small keelboats, the HK2654 is engineered to withstand demanding conditions without compromising on strength or functionality.
With its compact design, the block features nylon-resin sideplates packed with long-glass fibers, providing an excellent strength-to-weight ratio. The sheaves spin smoothly on high-load ball bearings with fitted races for low-friction operation, ensuring efficient performance under load.
The ball bearings, sheave, and sideplates are all UV stabilized with a black additive for maximum protection against the elements, making this block highly durable even in harsh marine environments.
