Shackles guide
Types of Shackles Available
Shackle Types We Offer
Elko Wire Rope supplies a complete range of shackle types to suit any rigging or lifting task:
- Anchor Shackles (Bow Shackles): Designed with a large rounded body for multi-directional loading and better side load tolerance.
- Chain Shackles (D-Shackles): With a narrower profile, ideal for straight-line tension and chain connections.
- Screw Pin Shackles: Quick and easy to assemble and disassemble for temporary or repeated rigging setups.
- Bolt-Type Shackles: Provide extra security for permanent or long-term installations, equipped with bolts, nuts, and cotter pins to prevent loosening from vibration.
- Round Pin Shackles: Preferred for certain tie-down or towing applications, allowing the pin to rotate with angular loads.
Each shackle type is available in a range of sizes, Working Load Limits (WLL), and material finishes to suit every need.

Safe Use, Inspection & Maintenance
Shackle Safety & Maintenance Guidelines
To maximize safety, performance, and longevity of your shackles, follow these best practices:
- Inspect Before Each Use: Check for distortion, cracks, corrosion, or pin wear.
- Install Correctly: Ensure the load is properly aligned and avoid shock loading or exceeding the rated Working Load Limit (WLL).
- Routine Maintenance: Keep shackles clean and lubricated; replace any that show signs of wear or deformation.
- Proper Storage: Store in dry, clean conditions to prevent corrosion, and organize by size or type for easy access.
Following these practices helps ensure safe lifts and compliance with industry regulations.

Shackle Size & WLL Chart
Shackle Size and Working Load Limit Chart
Typical working load limits for standard carbon steel bow shackles (6:1 design factor), by bow diameter. Alloy shackles like the Green Pin Super line carry more at the same size. Always rig to the WLL stamped on the shackle.

|---|---|---|
| 3/16 | 0.33 | 730 |
| 1/4 | 0.5 | 1,100 |

Sizing a shackle: work out the load on that connection, including sling angle and any side loading, then pick a shackle whose stamped WLL meets or beats it and matches the rated capacity of the sling it connects. For pin types, side-loading reductions and when to retire a shackle, read our guide to shackle types and their uses. For the sling side, see the wire rope sling capacity chart.
Questions about shackles
What is a shackle used for?
A shackle is a U-shaped metal connector used in rigging, lifting, towing, and securing loads by connecting chains, ropes, or lifting slings.
What are the different types of shackles?
The most common types are anchor shackles (bow shackles), chain shackles (D-shackles), screw pin shackles, bolt-type shackles, and round pin shackles.
What’s the difference between anchor and chain shackles?
Anchor shackles have a rounded bow that allows for side loading, while chain shackles have a narrower profile and are ideal for straight-line pulls.
When should I use a screw pin shackle?
Screw pin shackles are best for temporary or quick-assembly applications where the pin needs to be frequently removed.
What are bolt-type shackles used for?
Bolt-type shackles provide added security and are ideal for long-term or permanent installations where vibration could loosen a pin.
How do I determine the right size shackle?
Choose a shackle based on the load weight, pin diameter, body size, and compatibility with your slings or lifting gear.
What materials are shackles made of?
Shackles are typically made from forged alloy steel, stainless steel, or galvanized carbon steel for corrosion resistance.
Are shackles rated for overhead lifting?
Yes, shackles rated with a Working Load Limit (WLL) and manufactured to ASME or ASTM standards can be used for overhead lifting.
What is the Working Load Limit (WLL) of a shackle?
The WLL varies by shackle size, material, and design. Always refer to the manufacturer’s markings on the shackle body.
Do shackles require inspection?
Yes, shackles should be inspected before each use for signs of wear, deformation, corrosion, or damaged pins.
Can I use a shackle with a bent pin or body?
No. Shackles with any signs of bending, warping, or wear must be removed from service immediately.
What standards should shackles comply with?
Shackles should meet ASME B30.26, ASTM A153, and OSHA standards depending on the application.
Are there color-coded shackles?
Some manufacturers use color codes for quick identification of size or WLL, but always verify with the stamped ratings.
Can I use shackles in marine environments?
Yes, stainless steel or galvanized shackles are suitable for saltwater or corrosive conditions commonly found in marine use.
How tight should a shackle pin be?
Thread a screw pin in until the shoulder seats fully against the ear, then stop. Never back it off to line it up with the load. If the shackle stays rigged or sees vibration, use a bolt-type shackle or mouse the screw pin with wire.
Should I use cotter pins with bolt-type shackles?
Yes, cotter pins are used to prevent bolt-type shackle pins from backing out due to vibration or movement.
Can I side-load a shackle?
Bow (anchor) shackles can be side loaded at reduced capacity. Under ASME B30.26 they keep 70% of their WLL at 6–45° off-line and 50% at 46–90°, and should never be loaded more than 90° off-line. D (chain) shackles should not be side loaded.
What’s the difference between domestic and import shackles?
Domestic shackles are typically made to tighter quality controls and certifications, whereas imported shackles may vary unless certified.
Does Elko Wire Rope supply shackles?
Yes, Elko Wire Rope provides a wide range of high-quality shackles suitable for industrial lifting and rigging needs.

You can purchase certified heavy-duty shackles directly through Elko Wire Rope’s Shackles category.
