Ronstan SHOCK Pulley Rings RF8080




The Ronstan Shock Block is a SHeaveless blOCK designed for a wide range of uses. This lightweight and versatile block is an alternative to a traditional block. The best part is they only weight 2 grams each, yet have a working load of 175kg, while breaking load is 350kg. They can be lashed, spliced, or simply tied. Use them for halyards, control lines, trapeze systems, travelers… the list goes on!

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.

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 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. Small & hi-tech line specialists SHOCKS accept lines from 1.4mm up to 5mm and function just as well with hi-tech uncovered braids as with traditional double braids.
They are available in color choices to help keep complicated rigging configurations more organized.
