RONSTAN Fiddle Blocks - Overview |
Ronstan Core Fiddle Blocks
Ronstan Core Blocks™ Series 60 Fiddle Blocks are
a true all round solution. A tuned 2-stage bearing system provides
excellent
performance
across the full
working load range with an integrated thrust bearing feature
and the resilience
to handle high dynamic or static loads. Acetal sheave, alloy
cheeks and stainless fixings complete the durable package. For
reliability and a long service life, these blocks are the right
choice for
sheets,
halyards and control line applications for cruising and racing. Fiddle
blocks incorporate an integrated becket through the hub of the
lower sheave, and are ideal for creating simple vang and mainsheet
systems up to 4:1 on sailboats to 12m (40ft).
Ronstan All Purpose Fiddle Blocks
Ronstan Series All purpose (AP) fiddle blocks are
a great all around solution. Self-lubricating Acetal polymer
sheaves running
on polished
stainless steel
races perform equally well with dynamic loads and high static
loads.
For durability and a long service life, these blocks are
the right choice for sheets, halyards and control line applications
for cruising and racing.These fiddle blocks are ideal for
fine tune mainsheet tackles, cunninghams, boom vangs, backstays
and other control line purchase systems.
Ronstan Small Boat Fiddle Block
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.
Ronstan Big Boat Fiddle Blocks
Ronstan Roller Ball Orbit Fiddle blocks™ are
a no-compromise product range developed to meet the demands and
expectation of
the very
dedicated
and
increasingly professional racing sailor. Side cheeks incorporating
head structure
and hub are precision machined as a single part from solid alloy,
leaving material only where it contributes to the load carrying
capacity of the block and eliminating the need for additional
fasteners. The Orbit sheave has captive Acetal ball bearings
for side thrust
loads, eliminating the need for side retainer plates. This reduces
weight and allows for a wider bearing surface that can accommodate
longer Torlon® needles – achieving a substantially higher
strength-to-weight ratio. Spreacher blocks can accommodate a
second spinnaker sheet for sail changed or for an outboart genoa
sheet for racing.
Ronstan Utility Fiddle Blocks
The RONSTAN Fiddle Blocks have stainless steel
cheeks and Acetal sheaves ensure a long service life with virtually
no maintenance.
Hollow
rivets
in
the block
heads can be fitted with shackles, which can also be used to
add a becket for extra purchase. These blocks can be used as
a vang, cunningham and trapeze retriever systems on dinghies,
leech line
tackles,
bunk adjusters
etc
on
larger yachts
