Single Swivel Pulley Block – 35 mm Sheave for 3–8 mm Rope
This single swivel pulley block is engineered for demanding marine applications, providing a reliable solution for guiding lines on sailboats and other vessels. With its 35 mm sheave and robust build, it handles heavy loads while remaining lightweight and resistant to corrosion. It’s ideal for various rigging tasks – use it for sheets, control lines, vangs, or tackles on small to mid-sized boats. The freely swiveling eye allows the block to align with the direction of pull, reducing rope chafe and ensuring smooth, safe operation during maneuvers.
Key Features:
- High Load Capacity: Rated for a safe working load of 400 kg (with a breaking strength of 800 kg), this block confidently handles strenuous hauling and trimming tasks. You can rely on it for raising sails, tensioning control lines, or lifting gear without worry.
- Swivel Head Design: A full 360° rotating shackle prevents rope kinks and keeps the block properly oriented under load. This feature enhances safety and efficiency by allowing the rope to run freely in any direction without binding.
- Smooth Sheave Performance: The 35 mm sheave is precision-molded to accommodate 3–8 mm diameter ropes, ensuring minimal friction and smooth movement even under heavy strain. This translates to easier sail adjustments and less wear on your lines.
- Durable, Lightweight Construction: The side plates are made from a special fiberglass-reinforced polyamide composite, making the block stronger and lighter than traditional metal ones. This material won’t rust in saltwater and offers top-tier resistance to UV and marine corrosion, guaranteeing long service life. Weighing only ~0.05 kg and about 55 mm in length, it’s easy to install in tight spaces and won’t add unnecessary weight aloft.
As part of FINMAX’s EVAL Speed Hard series, this pulley block delivers an exceptional blend of strength, durability, and ease of use. It’s a smart upgrade for any sailing enthusiast or marine professional seeking dependable hardware that outperforms standard metal blocks. Whether you’re cruising or racing, this block’s high performance and resilience will enhance your boat’s rigging system.
