Integrated Becket for Purchase Systems. T316 Stainless Steel Hardware. Available in 35mm & 50mm Sizes.

Overview

Build powerful rigging systems with the RiaYer Single Swivel Becket Block. This essential pulley features an integrated Becket (anchor point) at the bottom, allowing you to start a line directly from the block to create 3:1 or 4:1 mechanical advantage systems. Constructed with a hybrid blend of T316 Marine-Grade Stainless Steel load straps and a lightweight, impact-resistant body, it is engineered to withstand high working loads while maintaining a compact profile. Whether for mainsheets or vangs, the 360° swivel head ensures your lines run smooth and twist-free.

Key Features

  • ⚓ Integrated Becket Anchor: The reinforced stainless steel becket allows you to tie off the line directly to the block, essential for creating block-and-tackle purchase systems.
  • 🔄 360° Swivel Head: Designed with a free-rotating head that aligns automatically with the load, effectively eliminating line twists and jamming during operation.
  • 🛡️ Hybrid T316 Construction: Combines T316 Stainless Steel hardware for maximum corrosion resistance and strength, with a reinforced Nylon body to keep the block lightweight.
  • 💪 Impressive Load Capacity: Built tough—the 35mm model supports a working load of 1,760 lbs, while the 50mm model handles up to 3,100 lbs (1406 kg).
  • ⚙️ Smooth Delrin® Bearings: Low-friction Delrin ball bearings ensure the sheave spins freely, providing precise control even under heavy dynamic loads.
