High strength and performance for unlimited uses
The Ronstan RF8080R-2 SHOCK Sheaveless Block 5mm (Pair)
Red is an excellent attachment option for limitless
applications including numerous high performance dinghy and small
sailboat rigging applications like tweakers, vangs, trapezes,
cunninghams, barber haulers and kite bridles. These blocks are also
handy on larger boats for uses such as lazy jacks, sail covers,
tie-downs, ladder and motor hoists. It is the obvious choice for
those kitesurfers, paragliders, control line deflections and
purchase systems that require a lightweight high load capacity
block.
Ultimate durability
With no moving parts SHOCKS provide ultimate durability and are
maintenance free. They are ideal where sand and grit would
compromise a bearing system or where regular flushing out isn’t
possible. Their gentle 3-dimensional geometry is kind on lines, but
is strong enough to cope with poor leads.
Soft attachment specialists
The Ronstan RF8080R-2 SHOCK Sheaveless Blocks are
designed primarily for soft attachment, spliced to a line end or
lashed in place. The elongated attachment aperture is also ideal
for webbing attachment, ensuring the intended orientation is
maintained.
Hidden performance
At a mere 2.5g (0.1 oz), SHOCKS are outstanding performers in the
strength and weight stakes. The clever design and exacting
finishing also provide excellent free running at moderate changes
of angle. Small and hi-tech line specialists, SHOCKS accept lines
from 1.4mm (1/16) up to 8mm (5/16) and function just as well with
hi-tech uncovered braids as with traditional double braids.
