Lazy Jacks contain mainsails during reefing and dousing. They work exceptionally well with full battened mains, but are also used with conventional sails. Kits include pre-swaged vinyl coated stainless cable, ball bearing blocks, eyestraps, line, a cleat, fasteners, and pictorial instructions. NOTE: Shipping price may vary due to weight of items ordered. Additional charges may be added. If you need a quote please e-mail.
