Violin pulley | BF-D® Block-Friction
Nodusfactory's Block-Friction® FrD duralumin anodized pulley is a top-of-the-range product offering numerous advantages in terms of performance, durability and ease of use. Exceptional strength-to-weight ratio (10 times lighter than a pulley), designed for high static loads. Block-Friction® pulleys can be used for 3:1 or 4:1 downhaul or mainsail hoists, as well as for cunningham adjusters or sheet point hoists on larger boats. Our violin pulleys are perfect for applications requiring low rope movement (speed) and low angle (the greater the deflection, the greater the friction).
