Wire Rope Sleeves

Aluminum Sleeve-Duplex Hourglass Ferrules

Aluminum sleeve-duplex hourglass ferrules are crimped or swaged terminations for wire rope splicing, designed for secure, lightweight, and corrosion-resistant connections in lifting, rigging, and cable assemblies. The hourglass profile provides a balanced grip across the wire rope strands, and the duplex design allows for two-point attachment or dual termination. Available from 3/64 inch to 5/8 inch wire rope diameter, these ferrules are made from high-grade aluminum with a machined and extruded finish. They are us

Key Benefits

What Aluminum Sleeve-Duplex Hourglass Ferrules Gives You

  • Lightweight construction reduces overall rigging system mass without sacrificing strength
  • High-grade aluminum resists corrosion in marine and outdoor environments
  • Duplex hourglass shape ensures even load distribution across the wire rope strands
  • Secure crimped or swaged connection prevents rope slippage under dynamic loads
  • Available in a wide range of sizes to match common wire rope diameters from 3/64 inch to 5/8 inch
  • Extruded and machined finish ensures consistent dimensional accuracy and surface integrity
  • Reduces fatigue and wear at termination points compared to poorly fitted or mismatched sleeves
Application Scenarios

Where Aluminum Sleeve-Duplex Hourglass Ferrules Is Used

  • Marine vessel rigging where wire ropes are exposed to saltwater and require corrosion-resistant fittings
  • Offshore platform mooring systems using lightweight, durable terminations for dynamic load conditions
  • Cranes and hoists in port operations where reduced weight improves lifting efficiency
  • Temporary industrial structures using wire rope guy lines with long-term exposure to weather
  • Rigging setups in mining and energy projects where lightweight yet strong connections are needed
  • Cable assemblies in construction hoists and suspended platforms requiring reliable rope termination
Who It Is For

How It Compares With The Alternatives

An honest read on where this pattern wins and where another one would serve you better.

AlternativeHonest Trade Off
Steel ferrulesAluminum is lighter and corrosion-resistant but has lower tensile strength; steel is stronger but heavier and prone to rust
Single-piece sleevesDuplex design allows dual termination or better load balance; single-piece may not distribute stress evenly
Cast aluminum sleevesExtruded and machined sleeves have tighter tolerances and consistent wall thickness; cast versions may have porosity or uneven walls
Crimped steel sleevesAluminum reduces weight and avoids galvanic corrosion but is less suitable for extreme shock loads
Use Guide

How To Use And Inspect Aluminum Sleeve-Duplex Hourglass Ferrules

  • Match the ferrule size to the wire rope diameter using the provided size table
  • Ensure the wire rope is fully inserted into the sleeve before crimping or swaging
  • Use calibrated crimping or swaging tools to achieve a secure, non-deforming connection
  • Inspect the crimped area for uniform compression and no gaps or distortion
  • Do not reuse a crimped ferrule after removal; always use a new one for safety
  • Retire the ferrule if the sleeve shows deformation, the crimp is loose, or the marking is unreadable
