Ronstan RF46101 Series 40 RTA Orbit Block Auto Single Link Head

Now you can enjoy the flexibility of setting up your fitout exactly
to suit yourself. With the Ronstan RF46101 Series 40 RTA
Orbit Block Auto Single Link Head, 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.

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
With auto models the sheet runs out smoothly and freely as soon as
the ratchet mechanism disengages. When engaged, 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.
