RONRF55301 - Ronstan Series 55 BB Orbit Block, Triple, Link Head
Code: RONRF55301
Price: $103.60
 

RONSTAN Multihull Blocks - Overview


Lightweight. Kilogram for kilogram of working load, Ronstan Series 55 Ball Bearing Orbit 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. Pair this assortment of blocks to produce up to a 9:1 mainsheet system for use on catamarans to 5.5 (18ft).
