A smart 90° connection, self-locking security and forged 316L stainless steel – designed for sailing applications where a standard shackle simply isn’t the right shape.

The Wichard Self-Locking Twisted Shackle solves a specific and common rigging problem: connecting two components that need to sit at a 90-degree angle to each other.

Instead of forcing a standard shackle into an unsuitable orientation, the twisted body naturally changes the direction of the connection by 90°.

Wichard combines this practical geometry with its self-locking pin system and forged 316L stainless-steel construction, creating a strong and secure solution for demanding sailing and yacht-rigging applications.

For Cavo Yachting, the product is available in two sizes:

8mm – Wichard #1224
10mm – Wichard #1225

Twisted Design – A Natural 90° Connection

The main difference between this product and a conventional D or bow shackle is immediately visible.

The body is twisted by 90°.

This allows two components with attachment points in different planes to connect more naturally.

Wichard specifically recommends the Twisted Shackle for applications where a 90° angle twist setup is required.

This can simplify an installation while helping connected hardware sit in the intended orientation.

Ideal for Blocks on Rails

One of the applications specifically identified by Wichard is the attachment of an:

Unarticulated component – such as a block on a rail

A conventional straight shackle may leave the block facing the wrong direction.

The twisted geometry changes the orientation by 90°, allowing the connected component to sit more naturally without requiring the shackle itself to work in an unsuitable position.

Suitable for Purchase Systems

Wichard also recommends the Self-Locking Twisted Shackle for:

Purchase Systems

In tackle and purchase systems, the correct orientation of blocks and attachment points is important.

The twisted shackle provides a simple mechanical solution when two connection points need to be aligned at 90° to one another.

Self-Locking Pin – Protection Against Vibration

The twisted shape is not the only advantage.

Wichard incorporates its self-locking system into both the 8mm and 10mm versions.

When correctly tightened, the pin locks into one of the indentations in the shackle body.

This design helps eliminate the risk of the pin becoming loose due to vibration – particularly useful aboard a sailing yacht, where deck and rigging hardware is constantly exposed to movement.

The concept is simple:

Tighten the pin → Pin engages with the indentation → Reduced risk of loosening from vibration

Forged 316L Stainless Steel

Both versions are manufactured from:

Forged Grade 316L Stainless Steel

This combines the corrosion resistance expected from quality marine stainless steel with the mechanical strength of a forged component.

For yacht and sailing hardware that may remain exposed to demanding marine conditions, this is an important advantage.

Wichard also manufactures these shackles in France.

Two Available Sizes

Cavo Yachting offers this product in the two larger sizes of Wichard’s Self-Locking Twisted Shackle range:

Wichard specifies these Working Load figures as WL for nautical applications.

Wichard #1224 – 8mm

The 8mm Wichard #1224 offers an excellent combination of compact dimensions, low weight and high load capacity.

Working Load: 1,000kg

Breaking Load: 3,000kg

Weight: only 67g

At just 67 grams, this twisted shackle provides a 1-tonne nautical Working Load and a 3-tonne Breaking Load.

It is a particularly attractive option when the installation requires a 90° connection but keeping hardware weight and dimensions low remains important.

Wichard #1225 – 10mm

For higher-load applications, the 10mm #1225 increases capacity substantially:

Working Load: 1,440kg

Breaking Load: 4,500kg

Weight: 127g

The larger 10mm version is designed for more demanding installations while retaining the same self-locking system, 90° twisted geometry and forged stainless-steel construction.

4,500kg Breaking Load

The larger #1225 provides an impressive:

Breaking Load: 4,500kg

Despite this high mechanical strength, the shackle weighs just 127g.

The two load figures should always be distinguished:

Nautical Working Load: 1,440kg
Breaking Load: 4,500kg

Breaking Load is not the normal permissible operating load. Product selection for nautical applications should be based on the appropriate Working Load and the requirements of the complete installation.

Detailed Dimensions

These dimensions and load ratings are the official specifications published by Wichard for parts #1224 and #1225.

Twisted Shackle or Standard Shackle?

The choice depends primarily on the orientation of the two components being connected.

A standard shackle is suitable when the connection points naturally align in the same plane.

The Wichard Twisted Shackle becomes particularly useful when the two components need to sit at approximately 90° to each other.

Instead of unnecessarily twisting the connected hardware, the shackle itself provides the required change in orientation.

This is exactly why Wichard recommends it for unarticulated parts such as blocks on rails and for purchase systems.
