Harken 40mm Carbo single block
This low friction, 40mm Carbo Boat Block from Harken is a suitable companion to their popular Black Magic Line, and is a lightweight, strong and reliable choice for all competitive boat racers.
The use of nylon resistant sidelplates ensures the Airbloc has a lower overall weight than the stainless steel straps of the classic models, whilst a reinforcement of densely packed glass fibres gives this boat block a high load bearing strength for safe, easy trimming.
