Harken 16mm Sheave (HK415)

16mm AirBlocks offer very high working loads in an extremely small, lightweight block.

These diminutive blocks feature a patented bearing system using stainless balls in a captive, grooved race and provide an honest 250lbs (113kg) safe working load.

They are perfect for the new, smaller synthetic control lines found on high-tech dinghies and are the obvious choice for competitive racers.
