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

FRD low-friction ring, in hardened anodized Duralumin ¬ anthracite grey
100% Dyneema® ® textile® crimping between rings, core and sheath
Weight optimized for sail applications
30% lighter than stainless steel
C-Tech® carbon friction rings, Nodus Factory™ are very light, reliable and highly resistant to friction for dynamic use. Essential aboard your sailboat with our textile connectors "Loops, Lock,..." to be able to optimize your deck plan for greater safety and performance. Carbon rings are around 10 times lighter than aluminum rings and 6 times lighter than steel rings. This lightness is a major advantage in applications where weight is a limiting factor, such as sailing or aviation.
Low Friction ring | Fr I-Tech® Dynamic

Block friction ring| Ring-Nub®
Ring-Nub® is an open spherical low-friction ring that withstands very high loads and is available for strings from 3 mm to 12 mm maximum. Ring-Nub offers a unique combination of advantages in terms of performance, durability and ease of use. It's an excellent choice for applications where friction must be minimized and strength maximized. See examples of NUB® low-friction ring applications with textile connectors (textile shackle, loop, erse, lock and hook) in the category PLUG & SAIL .
Violin pulley | Mickey-Rings® 3D adjustment
Nub 3D pulley for fine-tuning headsail sheets The Nub 3D pulley is a revolutionary pulley designed for fine-tuning headsail sheets. It features a unique 3D adjustment system that allows the angle of the pulley to be altered in three different directions. This allows precise control of headsail position and optimizes boat performance. Features: Materials: Body in high-performance technical polymer Maximum working load: 2500 kg. Compatible rope diameter: 4 mm to 10 mm.
