Cleveco
The Cleveco Single Swivel Top Pulley (60mm) is a heavy-duty marine block designed for smooth, efficient rope handling in sailing and rigging systems. Built in New Zealand and engineered for durability, this pulley features a 60mm Delrin sheave that delivers low-friction performance under load, making it ideal for demanding marine environments.
The wide sheave is specifically designed to handle high loads while reducing rope wear, with self-lubricating Delrin material using water as a natural lubricant for consistent, reliable operation. The sheave is housed within 14-gauge stainless steel straps, ensuring excellent corrosion resistance and long-term strength in harsh marine conditions.
Equipped with a swivel top head, this pulley allows free rotation under load, helping maintain correct alignment and reducing twisting in rope systems. This makes it especially suitable for dynamic applications such as mainsheet systems, halyards, and control lines where movement and load direction change frequently.
