Ronstan RF46102 Series 40 RTM Orbit Block Manual Single Link Head

Now you can enjoy the flexibility of setting up your fitout exactly
to suit yourself. The Ronstan RF46102 Series 40 RTM Orbit
Block Manual Single Link Head allows the ratchet mechanism
to be switched on or off as required. This is the preferred
mainsheet set-up for many top sailors.

Awesome ratchet block holding power
Quite simply, Ronstan Ratchet Orbit Blocks have the highest holding
power available. The sophisticated NC-machined sheave features
Generation 2 of our patented sheave cross-hole geometry. The Series
40 delivers up to 14:1 holding power.

Unique sheave design has 8 gripping faces which directly resist
loaded line movement
Traditional designs have an angled resistance to line movement. The
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
The sheave cross – hole geometry eliminates the ‘shuddering’
ease-out that you can expect from traditional v-groove ratchet
blocks.

Low profile stand-up kit allows 0 or 90 degrees
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
full articulation.
