Shock - 3/8" Line - 3/8" Webbing - Blue

The Sheaveless Black

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

SHOCKS 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.

Virtually limitless applications

The applications for SHOCKS are virtually limitless, including numerous high performance dinghy and small sailboat rigging applications including tweakers, vangs, trapezes, cunninghams, barber haulers and kite bridles. They are also handy on larger boats for uses such as lazy jacks, sail covers, tie-downs, ladder and motor hoists.

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 & 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.
