Hybrid Construction: T316 Stainless Steel Hardware + PA66 Nylon Body. Double Sheave Efficiency.

Overview

Optimize your rigging system with the RiaYer Double Sheave Marine Block Series. Available in both 35mm and 50mm sizes, these blocks feature a professional Hybrid Construction. We combine the structural integrity of T316 Marine-Grade Stainless Steel load straps with a lightweight, impact-resistant PA66 Nylon body. Inside, precision Delrin® ball bearings ensure low-friction operation. Whether you need the compact agility of the 35mm or the heavy-duty power of the 50mm, this series delivers reliable performance for mainsheets and control lines.

Key Features

  • ⚓ Composite T316 & Nylon Build: The perfect balance of strength and weight. Critical load parts are forged from T316 Stainless Steel for rust resistance, while the body uses reinforced Nylon to reduce deck weight.
  • ⚙️ Double Sheave Design: Both the 35mm and 50mm models feature a dual-pulley configuration, doubling your mechanical advantage for easier line handling.
  • 🔄 Smooth Delrin® Bearings: Equipped with high-performance Delrin ball bearings that prevent jamming and ensure the sheaves spin freely even under dynamic loads.
  • 📏 Two Professional Sizes: Available in a compact 35mm version for smaller crafts/control lines and a robust 50mm version for mainsheets and higher loads.
  • 🔒 Fixed Head Stability: The stainless steel fixed head keeps the block aligned with the load direction, preventing twists and tangles in your rigging.
