Built for dependable performance in demanding marine settings, it features a swiveling head that makes on‑deck rigging adjustments effortless.

• Cast Single Sheave: Reliable, low‑maintenance pulley designed for light pulley applications with steady performance.
• Product Code & Compliance: K284; NZ Code: K284 AM 29/05/2021, ensuring clear specification and project compliance.

Designed for sailors who demand longevity and predictable performance, this Mame Swivel Block minimizes wear on lines while delivering dependable rotation under load. The marine‑grade stainless steel construction keeps rust at bay in years of salt spray, making it a prudent choice for coastal cruising and everyday sailing setups where a light, reliable pulley is needed. For maintenance, rinse with fresh water after exposure to salt spray, inspect the swivel regularly, apply a light lubricant if movement feels stiff, and store in a dry area to prevent corrosion or grime buildup on the sheave and swivel.
