The XX holds loads 50% higher
than any conventional clutch
and is smooth and controlled
to release. Optimised for high
performance 8-12mm diameters,
the XX fills the critical load
holding gap between clutches
and high load ZS jammers.
As well as the standard clutch, a
Lock Open version, the XX0812/L,
is also available which allows the
line to run freely in both directions
with the handle closed, important
for spinnaker and mainsheet
applications where locking off
is only occasionally needed. The
XX0812/L also features an automatic
jaw release when the load is taken
on a winch. A standard XX can be
upgraded to a Lock Open version
with XX-MLDG or XX-LCK kit.
Line feeding into the XX0812 :
Using a long screwdriver, place shaft
through front bullseye and locate
tip on front face of lower jaw. Push
backwards until the jaw stops. With
the jaws in this position raise and
fully open the handle. This locks the
jaws back at their biggest clearance
and allows easy threading of your
new rope.
This process is not necessary for the
XX Lock Open Version.

Safety Note : In stronger winds,
rope damage can be caused
releasing a highly loaded
line. This can be prevented by
transferring the rope load to
the winch before release.
XX0812/L Lock Open Clutch Operation
1.
With the lock open latch in the UP
position the line runs freely through the XX
2.
When the latch is pushed DOWN with the
handle closed, the line is held secure
3.
To release the line, the handle can then be
opened, OR
4.
With the handle in the closed position,
move the lock open latch to the UP
position. When the load is taken securely
on a winch the jaws will automatically
release, allowing the line to run free, with
the handle still in the closed position. The
jaw will remain open until the latch is
returned to the down position, even if
the handle is cycled.
With your new rope threaded you
can now close the handle. As the
handle closes, the XX clutch will
automatically engage the rope.
Release :
As a safety feature, no
release action begins until the handle
is rotated beyond 60 degrees.
To protect the user and rope fibre,
normal hand pressure will not
release the rope above this load.
Important :
Always start the release
process with the handle in the closed
position for full release efficiency.
If at any time you only part open
the handle we advise completely
opening and closing (cycling)
the
handle, with the line secured on the
winch, to ensure the mechanism is re-
set for full release next time. Failure
to do this will result in poor holding
power and worn jaw surfaces.
Sleeving :
Secondary sleeving
(internal or external) of the
rope significantly improves the
performance levels of any clutch
or jammer. Any external sleeving
should be a very tight fit. If you are
going to sleeve your rope, ensure
that the overall diameter does not
exceed 12mm and has a taper to
run freely through the clutch.
Core
inserts provide the smoothest
transition for fast line speed
applications.
