Heavier duty mastbands in bronze. These incorporate heavier lugs, drilled for shackles, a broader step to fit onto masts and spars better without slipping. Depending on envisaged loading, these may safely be used as cranse irons and rigging attachments on small craft.
OK up to about 1 ton. Warning – any craft over about 20 ft, these are unlikely to be strong enough as cranse irons.
