Marine Guide Single Pulley Block specifically designed for sailboats, kayaks, and small watercraft rigging systems.
Technical Specifications
Material Composition: Built with a premium 316 stainless steel plate frame to survive harsh saltwater environments, paired with a self-lubricating composite nylon wheel to minimize rope friction.
Dimensions: Typically features an overall length of 73mm (2.87 inches) and a sheave wheel diameter of 40mm (1.57 inches).
Line Capacity: Designed with a smooth 6mm sheave groove, making it highly optimized for running lines between 4mm and 8mm in diameter (with a maximum rope capacity of up to 10mm).
Load Rating: Engineered with a maximum static load-bearing capacity of up to 500 kg (1,100 lbs).
Common Applications
Sailboat Rigging: Frequently used as an inline fairlead, lazy jack guide, or directional rope diverter for small dinghies and sports yachts.
Kayak Upgrades: Perfect for building custom anchor trolley systems or steering rudder line configurations.
General Utility: Due to its high weight rating, it is also widely used for gym cable equipment, outdoor sunshade canvas controls, and lightweight wire rope lifting setups.
If you are currently setting up a specific line configuration, let us know where you intend to mount it (e.g., deck, mast, kayak hull) or how many purchases (mechanical advantage) you need so we can recommend the right layout.
