With no moving parts this sheaveless block provides ultimate durability while being maintenance free. It is ideal where sand and grit would compromise a bearing system or where regular flushing out isn’t possible. It's gentle 3-dimensional geometry is kind on lines, but is strong enough to cope with poor leads.

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.

Applications are virtually limitless, including numerous high performance dinghy and small sailboat rigging applications including tweakers, vangs, trapezes, cunninghams, barber haulers and kite bridles. It is 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), this sheaveless block is an outstanding performer in the strength and weight stakes.
