Kilogram for kilogram of working load, Ronstan Ball Bearing
Orbit Fiddle Blocks™ are
the world’s lightest. The unique orbital design allows the
bearing to only be in the active areas of the floating sheave.
This minimises the mass of the inactive return race and hub.Weight
and bulk are further reduced in the different block configurations.
The ball bearing single and becket block has a through-sheave
becket arrangement. The result? The lowest weight possible.Multi-sheave
blocks have only single intermediate cheeks and an ultra-light
and efficient head arrangement. This gives a 30%
weight saving advantage over the nearest competitor. Other brands
just link together their single blocks. This results in unnecessary
double cheeks between each sheave, held together by a heavy steel
channel across the top of the block. These fiddle blocks are ideal
for fine tune mainsheet tackles, cunninghams, boom vangs, backstays
and other control line purchase systems.
