Ronstan Low Friction Shocks:


Available in four colour options – blue, grey and red with several attachment options, including webbing, pigtail, lashing and Dyneema® links, it will be the obvious choice for those kite surfers, paragliders, control line deflections and purchase systems that require a lightweight high load capacity block.


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.
NB: We know that Shocks™ are easily worn/damaged from salt and grit embedded in wet rope, and that nothing in this world is maintenance free. We always recommend fresh water rinsing of all hardware products.


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.



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.


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. Shocks™ accept lines from 1.4mm (1/16”) up to 8mm (5/16”) and function with hi-tech uncovered braids as with traditional double braids. They are available in colour choices to help keep complicated rigging configurations more organised.

Unlimited uses, including kitesurfing, paragliders, sports kites, power kites, stunt kites, depower kites, traction kites, for deflection or purchase system on control lines.

Anodised aluminium.
