Automatic and manual ratchet options.
Now you can enjoy the flexibility of setting up your fitout exactly
to suit yourself. Ronstan is the only company that offers a 40mm
ratchet block with both auto and manual engagement models*. With
automatic models, the ratchet mechanism engages when load is
applied, but switches off when it's released. This lets the sheet
run out smoothly and freely-great for rapid easing of the sheet
and for gybing asymmetric spinnakers. Manual modes allow the
ratchet mechanism to be switched on or off as required. This
is the preferred
mainsheet set-up for many
* Selected Series 40 models.
Awesome ratchet block holding power.
Quite simply, Ronstan Ratchet Orbit Blocks™ Series 40 have
the highest holding power available. The sophisticated NC-machined
features Generation 2 of our patented sheave cross-hole geometry.
The Series 40 delivers up to 14:1 holding power, almost double
that of our nearest competititor. The unique sheave design has
8 gripping faces which directly resist loaded line movement.
Traditional designs have an angled
resistance to line movement. Our Generation 2 design has straight
resistance faces which both distribute the load and minimise
rope wear. These faces are offset from the radial line, to draw
the rope down into the gripping area when under load.
Simple and secure attachment. The Dyneema® Link is easily fitted and is retained securely
by a moulded retainer clip. The flexible link can be left with
one end attached to the block when fitting - no more lost shackle
pins. The system is compatible with Dyneema®/Spectra® strops,
webbing and carbon connection points - much more so than steel
loop tops or shackles.
Smooth easing of sheets.
With auto models the sheet runs out smoothly and freely as soon
as the ratchet mechanism disengages. When engaged, and with manual
models, the sheave cross - hole geometry eliminates the 'shuddering'
ease-out that you can expect from traditional v-groove ratchet
Low profile stand-up kit allows 0° or 90° alignment.
Stand-up kits feature a clatter-free rubber boot. You can attach
the Dyneema® link so that the block is aligned with the stand-up
base or across it. It's a neat low-profile solution which allows
