Marine Pulleys & Blocks

Smooth Operation for Lifting and Rigging

Reduce friction and gain mechanical advantage with our high-quality Stainless Steel Pulley Blocks. Whether you are managing sail lines, setting up a flag pole, or designing a wire rope lifting system, our pulleys ensure smooth, reliable performance under load.

Choosing the Right Pulley Block

We manufacture a wide variety of blocks to suit specific rope types and applications:

1. Sheave Material: Nylon vs. Stainless Steel

• Nylon Wheels: Best for fiber ropes (paracord, dock lines, halyards). They are quiet, lightweight, and reduce wear on soft ropes.
• Stainless Steel Wheels: Essential for wire rope applications. They withstand the abrasion of steel cable and offer higher load capacities.

2. Block Configuration

• Single Sheave: For simple direction changes or light lifting.
• Double Sheave: Used to create block-and-tackle systems for lifting heavier loads with less effort.
• Swivel Eye vs. Fixed Eye: Swivel tops rotate 360 degrees to prevent ropes from twisting and tangling during operation. Fixed eyes provide a stable, rigid anchor point.

Built for the Sea

Our pulley blocks are constructed from stamped or cast AISI 316 Stainless Steel shell bodies, offering maximum protection against rust.

• Removable Pins: Many of our models feature removable axle pins, allowing you to easily mount the rope or replace the sheave without cutting the line.
• Smooth Rotation: Precision-machined axles ensure low friction and long service life.
