Professional Stop Sleeves - Wire Rope Fittings & Tools
Stop sleeves, also known as ferrules or swage sleeves, are metal sleeves crimped onto wire rope to create stops, secure loops, or join rope sections. These essential wire rope fittings provide reliable, permanent connections when properly installed with the correct crimping tools. From creating eye terminations and securing thimbles to forming stops and joining cables, quality stop sleeves offer strong, dependable connections for marine rigging, industrial cable systems, and general wire rope applications. US Rigging offers professional-grade stop sleeves in various sizes and materials, engineered for strength and reliable performance in demanding applications.
What are Stop Sleeves?
Stop sleeves are cylindrical metal sleeves that are crimped (compressed) onto wire rope using specialized crimping tools. The crimping process deforms the sleeve, creating a tight grip on the wire rope that holds securely under load. Stop sleeves are used to create permanent terminations, secure loops, attach thimbles, and form stops on wire rope and cable.
Key Characteristics of Stop Sleeves
- Crimped Connection: Compressed onto wire rope for permanent attachment
- High Strength: Properly crimped sleeves retain high percentage of rope strength
- Permanent: Cannot be removed once crimped
- Various Sizes: Available for different wire rope diameters
- Simple Installation: Requires proper crimping tool
- Reliable: Proven method for wire rope terminations
- Corrosion Resistant: Aluminum or copper for different applications
- Cost-Effective: Economical alternative to splicing or mechanical fittings
Types of Stop Sleeves
Single Sleeves
Standard cylindrical sleeves for general-purpose applications, crimped over single or double wire rope.
Key Features:
- Simple cylindrical design
- Most common type
- Various lengths available
- For single or double rope
- Economical option
Double Sleeves (Duplex Sleeves)
Two-hole sleeves designed for joining two wire ropes or creating specific configurations.
Key Features:
- Two parallel holes
- For joining two ropes
- Specific rigging applications
- Keeps ropes parallel
Stop Sleeves (Stops)
Short sleeves crimped onto rope to create a stop or prevent movement through hardware.
Key Features:
- Short length
- Creates stop on rope
- Prevents rope from pulling through
- Simple and effective
Materials
Common Materials
- Aluminum: Most common, lightweight, good for stainless steel wire rope, corrosion resistant
- Copper: Softer material, good grip on rope, traditional choice for galvanized rope
- Brass: Corrosion resistant, good for marine applications
- Steel: High strength for heavy-duty applications
Important: Match sleeve material to wire rope material. Aluminum sleeves for stainless steel rope, copper sleeves for galvanized rope. Mismatched materials can cause galvanic corrosion.

Proper Installation
Installation Requirements
- Proper Tool: Use correct crimping tool for sleeve size
- Correct Size: Sleeve must match wire rope diameter
- Proper Crimp: Follow manufacturer's crimping specifications
- Number of Crimps: Typically requires multiple crimps along sleeve length
- Crimp Pattern: Crimp in proper sequence and spacing
- Inspection: Verify proper crimp before loading
Creating an Eye Termination
- Insert Thimble: Place thimble in desired loop size
- Thread Rope: Pass rope end back through sleeve alongside standing rope
- Position Sleeve: Slide sleeve over both rope sections
- Crimp: Crimp sleeve using proper tool and pattern
- Inspect: Verify crimp quality and rope security
Critical Installation Warnings
- Proper Tool Required: Never use pliers or improper tools - will not crimp correctly
- Correct Size: Wrong size sleeve will not hold properly
- Adequate Crimps: Insufficient crimps can cause failure under load
- Material Match: Use correct sleeve material for wire rope type
- Follow Specifications: Always follow manufacturer's crimping instructions
- Inspect Before Loading: Verify proper installation before applying load
Choosing the Right Stop Sleeve
Key Considerations
- Wire Rope Diameter: Sleeve must match rope diameter exactly
- Material: Aluminum for stainless rope, copper for galvanized rope
- Application: Eye termination, stop, or joining
- Length: Longer sleeves provide more holding power
- Environment: Corrosive environments require appropriate materials
- Load Requirements: Ensure sleeve is rated for your application
- Crimping Tool: Ensure you have proper tool for sleeve size
- Quantity: Purchase adequate quantity for your project
Inspection & Quality Control
Inspection After Installation
- Visual Inspection: Check for proper crimp deformation
- Crimp Pattern: Verify all required crimps were made
- Sleeve Position: Ensure sleeve is in correct position
- Rope Condition: Check that rope wasn't damaged during crimping
- Pull Test: Perform pull test if required for critical applications
- No Gaps: Verify no gaps between rope and sleeve
Ongoing Inspection
- Regular Inspection: Check crimped connections periodically
- Corrosion: Look for corrosion at sleeve/rope interface
- Rope Condition: Inspect wire rope for wear or damage
- Sleeve Integrity: Check for cracks or deformation
- Load Performance: Verify connection maintains integrity under load
Frequently Asked Questions
What's the difference between aluminum and copper sleeves?
Aluminum sleeves are typically used with stainless steel wire rope - they're lightweight, corrosion-resistant, and won't cause galvanic corrosion with stainless steel. Copper sleeves are traditionally used with galvanized wire rope - they're softer and grip well. Using the wrong material combination can cause galvanic corrosion. Always match sleeve material to rope material.
Can I crimp sleeves with pliers or a hammer?
No. Proper crimping requires a specialized crimping tool designed for the sleeve size. Pliers, hammers, or other improvised tools will not create a proper crimp and the connection will likely fail under load. Invest in the correct crimping tool or have sleeves professionally crimped for safety-critical applications.
How many crimps do I need on a sleeve?
The number of crimps depends on sleeve length and wire rope diameter. Generally, sleeves require multiple crimps spaced along their length. Follow the manufacturer's specifications for your specific sleeve size. Typical patterns include 2-4 crimps for standard sleeves. More crimps provide better holding power.
What percentage of rope strength do crimped sleeves retain?
Properly crimped sleeves typically retain 80-95% of the wire rope's breaking strength, depending on the sleeve type, material, and installation quality. This makes them very effective for creating strong terminations. However, improper crimping can significantly reduce strength, which is why proper tools and technique are critical.
Can I reuse a crimped sleeve?
No. Once a sleeve is crimped, it's permanently deformed and cannot be removed or reused. If you need to redo a termination, you must cut off the crimped sleeve and use a new one. This is why it's important to get the installation right the first time and verify everything before crimping.
