Violin pulley | Mickey-Rings® 3D adjustment
BF-M®, the 3D Mickey-ring fiddle block is a set of 3 connection points, ideal for efficient 3D adjustment of the genoa tack. Lightweight and compact, the multiaxial 3D fiddle block allows perfect alignment of connections at different angles, with each friction ring rotatable and movable (10 times lighter than a pulley), designed for heavy loads.< Easy to set up, this multiaxial 3D friction ring system rotatable up to 180° will produce minimum friction and wear on your ropes. They can be used for just about anything and with any type of rope, although beware that some Technora® ropes have an aggressive grip.
