Violin pulley | BF-D® Block-Friction

20273

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).

Description

The multiaxial 3D violin pulley allows perfect alignment of connections at different angles, with each friction ring adjustable and mobile.

+ Application

  • For 3:1 or 4:1 downhaul or mainsail hoists, as well as for cunningham adjustment hoists or sheet point hoists on larger boats.
  • Ideal for applications requiring low rope movement (speed) and low angle (the greater the deflection, the greater the friction).
  • A 60° angle gives 100% of the load, a 180° angle 200% of the load.
  • The textile connection allows the load to self-align, reducing fatigue.
+ Repairability
  • Category 1 reparability
