Ronstan 10mm Shock Block 3/8"-Red Murrays Part# 21-8081 The Sheaveless Ronstan Shock Block: 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 Shock Blocks 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:Shock 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. Virtually Limitless Applications:The applications for Shock Blocks 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), Shock Blocks are outstanding performers in the strength and weight stakes. The clever design and exacting finish also provide excellent free running at moderate changes of angle. Shock Blocks 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.
