Ertacetal Sheaves for Standard & Eco Series Blocks – For Laid Rope

Our Sheaves for Standard and Eco Series Blocks – Designed for Laid Rope

Our sheaves, specially developed for the Standard and Eco Series blocks, are optimized for use with laid rope. Made from Ertacetal (POM), a high-performance engineering plastic, they combine strength, smooth performance, and long-lasting durability — even under heavy loads and demanding marine conditions.

Features:

• Made from Ertacetal (POM): strong, low-friction, and wear-resistant

• Specifically designed for 3- or 4-strand laid rope

• Suitable for both Standard and Eco Series blocks

• Excellent resistance to UV, saltwater, and abrasion

• Ensures smooth running and reduced wear on rope

• Available with or without extra slide bearing for heavier loads and even lower friction

Perfect for classic yachts and tall ships where traditional rigging is combined with modern reliability.
