Special Features

  • 【Create a powerful 4:1 mechanical advantage system】:Lift heavier with less effort. Unlike single pulleys, this 2-pack set of double-sheave blocks is designed to work together. By rigging them with rope, you can build a highly efficient block and tackle hoist that reduces the lifting weight by up to 75% (4:1 ratio)—perfect for effortlessly hoisting kayaks, bikes, or heavy storage boxes to your ceiling.
  • 【Hybrid 316 stainless steel & reinforced nylon】:The best of both worlds. The load-bearing shackle and axles are forged from 316 Marine Grade Stainless Steel for ultimate rust resistance, while the body is molded from high-strength Reinforced PA66 Nylon. This composite design makes the pulley 100% corrosion-proof and ideal for saltwater marine rigging or outdoor camping setups.
  • 【Lightweight, silent & surface-friendly】:Strength without the bulk. The nylon body makes these M35 blocks significantly lighter than all-metal alternatives, reducing sag in your lines. Plus, the soft nylon housing won't scratch your boat deck, car roof, or paintwork if it swings against them, and the self-lubricating wheels operate silently without metal squeaking.
  • 【Stable fixed eye for tangle-free rigging】:Essential for double pulley systems. The top U-shackle pivots 180 degrees but maintains a fixed orientation (non-swivel). This is a crucial feature when running four strands of rope in a hoist system, as it prevents the block from spinning and twisting the lines into a knot, ensuring a smooth, straight lift every time.
  • 【High capacity compact M35 design】:Small size, heavy lift. Despite its compact 35mm wheel size (Total Length: 95mm), the double-axle structure supports a Safe Working Load of 250kg (550 lbs) per unit. The U-grooves are optimized to securely grip paracord and braided ropes up to 8mm (5/16 inch), preventing slippage during operation.

Description

Helffer Composite Double Pulley: The Rust-Proof Lightweight Solution. Traditional all-metal pulleys are heavy, can rust, and might scratch your expensive equipment. The Helffer Series solves this by combining the best of two worlds: the structural strength of 316 Stainless Steel hardware with the lightweight durability of a Reinforced Nylon Body. Why choose this Hybrid Nylon/316 Steel design? 100% Corrosion Resistance: The body is plastic (won't rust), and the hardware is 316 Marine Steel (resists salt). It is the ultimate outdoor pulley. Deck & Gear Friendly: The composite nylon shell is softer than steel. If it swings and hits your kayak, boat deck, or car hood, it won't chip the paint or leave a dent. Ultra-Lightweight: Perfect for portable gear, backpacking, or rigging on lightweight structures like tents and awnings. Common Uses: Marine: Kayak anchor trolleys, boat flag lines. Outdoor: Hanging bear bags (camping), tensioning sun shades. Home: Curtain tracks, light fixture suspension, garage organization.
