Product Information

Full details

This SecureFix Direct Long Dee Shackle with Captive Screw Pin is designed for securely connecting chains, straps, and other rigging components. Its primary benefit is the captive screw pin, which prevents accidental loss, ensuring a reliable connection. A key consideration is its specific 4mm size, which dictates its load capacity and suitability for particular applications. This shackle is constructed from durable stainless steel, offering excellent resistance to rust and corrosion, making it particularly well-suited for harsh environments.

FAQs

What is the working load limit (WLL) for this shackle?

The working load limit is not specified in the product information. Always ensure the load applied does not exceed the shackle's capacity, which is typically determined by its material and dimensions. For critical applications, consult with a rigging professional.

Is this shackle suitable for lifting heavy loads?

This 4mm stainless steel shackle is designed for general rigging and securing purposes. For lifting heavy or critical loads, professional advice should be sought to ensure the correct size and rated equipment is used.

How do I prevent the captive screw pin from rusting?

While stainless steel offers excellent corrosion resistance, regular cleaning and avoiding prolonged exposure to harsh chemicals or stagnant saltwater will help maintain its condition. A light coating of marine-grade lubricant can also offer protection.

Can I replace the captive screw pin if it gets damaged?

No, the captive screw pin is permanently attached to the shackle body. If the pin is damaged, the entire shackle will need to be replaced.

What does 'Long Dee Shackle' mean?

A 'Long Dee Shackle' refers to the elongated shape of the 'D' in its design, which can sometimes offer more space for connecting rigging components compared to a standard Dee shackle.

What are the external dimensions of the shackle?

The external dimensions are: A = 32mm (overall length), B = 16.5mm (inner width), C = 8.2mm (pin diameter), D = 3.5mm (material thickness).

Troubleshooting

Screw pin is difficult to tighten or loosen.

Ensure there is no debris or corrosion hindering the threads. Clean the threads if necessary. Apply a small amount of marine-grade lubricant if needed.

Visible signs of corrosion on the surface.

Clean the affected area with a mild abrasive pad and water. If corrosion is deep or structural, the shackle may need replacement.

Shackle does not seem to fit the intended chain/strap.

Verify the dimensions of the shackle (8.2mm pin diameter, 16.5mm inner width) against the chain link or strap eyelet. Ensure compatibility of load ratings.

Pros and Cons

Pros

  • Secure and reliable connection due to the captive screw pin.
  • Excellent resistance to rust and corrosion, extending product lifespan.
  • Robust stainless steel construction for durability.
  • Versatile for numerous applications, especially in marine environments.
  • Prevents loss of critical components like the screw pin.

Cons

  • Specific 4mm size may limit its use for very heavy-duty applications.
  • Requires periodic inspection to ensure optimal performance.
  • The captive pin design, while secure, can sometimes be slightly less convenient for rapid changes compared to a fully removable pin.

Setup, Compatibility & Care

Setup:

  1. Align the screw pin with the shackle eye.
  2. Insert the pin and hand-tighten the screw.
  3. For maximum security, use a suitable tool (e.g., pliers or a wrench) to further tighten the screw. Ensure it is snug but do not overtighten.

Compatibility:

This shackle is designed for use with chains, ropes, and straps with compatible load ratings and diameters. Always ensure that the working load limit (WLL) of the shackle is appropriate for the intended application and does not exceed it. Refer to the product specifications for precise dimensions.

Care:

  • Regularly inspect the shackle for any signs of wear, corrosion, or damage to the pin or body.
  • Clean the shackle periodically with a soft cloth, especially after exposure to saltwater or harsh chemicals.
  • Avoid using abrasive cleaners or tools that could scratch the stainless steel surface.
  • Store in a dry place when not in use to further prevent corrosion.
