SHOCKS™
RONSTAN SHEAVELESS BLOCKS
Some small line rigging applications do not require ball bearing blocks, so Ronstan has introduced its Shocks™ Sheaveless compact blocks. Designed to fit a wide array of small diameter rigging uses, the new Shocks™ are claimed to be perfect for moderate load uses where minimal purchase is required.
The compact Shocks™ are carefully engineered to work well even if the load alignment is not straight. Made from anodized aluminium they weigh only 2.5g (0.01 oz.), yet can carry up to 350kg of break-load force. The Shocks™ soft attachment compatibility make them suitable for use in 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 ladder and motor hoists, lazy jacks, sail covers, and tie-downs.
Shocks come in two sizes and accepts 1.4mm to 10mm (1/16" - 3/8") line diameters for running rigging and can be used with up to 10mm (3/8") webbing attachments. They are available in three colour choices to help keep complicated rigging configurations more organised.
