Wichard HR Bow Shackle Ω 20mm High Resistance

28,000kg Breaking Load. 8,800kg nautical Working Load. Forged HR construction for the most demanding connections.

When loads become serious, the strength and quality of every connection point matter.

The Wichard HR Bow Shackle Ω 20mm #11248 is engineered for applications requiring very high mechanical strength. Its forged HR 17-4 PH stainless-steel construction combines outstanding load capacity with the versatile, wide geometry of a Bow / Ω shackle.

The result is a professional marine fitting designed for demanding sailing and rigging applications where both exceptional strength and additional connection space are required.

HR – High Resistance Stainless Steel

The HR designation stands for High Resistance.

Wichard manufactures the #11248 from:

HR 17-4 PH Stainless Steel

This high-resistance stainless-steel grade, combined with forged construction, provides outstanding working and breaking loads.

According to Wichard, an HR shackle can offer up to 60% greater resistance than a comparable shackle manufactured from 316L stainless steel.

For high-load marine applications, this makes the HR range particularly attractive when exceptional mechanical strength is required.

Forged Construction for Extreme Loads

The #11248 is a forged Bow Shackle, engineered specifically for demanding loads.

Its forged construction and HR stainless-steel material allow the 20mm shackle to achieve an exceptional 28,000kg Breaking Load.

This combination makes the #11248 a serious piece of marine hardware for installations where ordinary lower-strength shackles may not provide sufficient capacity.

Bow / Ω Shape – More Room for Connections

Strength isn’t the only advantage of the #11248.

Its characteristic Bow / Ω geometry creates a wider internal area than the narrower profile of a conventional D shackle.

Wichard specifically recommends this design when ample room is required and highlights the possibility of attaching several lines or cables.

This makes the Bow / Ω shape particularly useful when you need:

• High load capacity
• More internal connection space
• The possibility of attaching several compatible lines or cables
• Greater flexibility than a narrow D-shaped connection

20mm Diameter

The Wichard #11248 has a nominal diameter of:

Ø20mm

This substantial construction is designed for serious loads, providing a nautical Working Load of 8,800kg and a massive Breaking Load of 28,000kg.

Before installation, always check the complete dimensions against the lines, cables, eyes and fittings involved in the intended connection.

Nautical Working Load – 8,800kg

For nautical applications, Wichard specifies:

Working Load: 8,800kg

This is the Working Load figure specified by Wichard for nautical applications.

An 8.8-tonne Working Load makes the #11248 a serious option for appropriately specified high-load sailing, yacht and rigging applications.

Breaking Load – 28,000kg

The Wichard HR Bow Shackle 20mm reaches an exceptional:

Breaking Load: 28,000kg / 28 tonnes

This is one of the strongest selling points of the #11248 and demonstrates the mechanical performance of Wichard’s forged HR construction.

The Breaking Load must not be confused with the Working Load and should not be considered the permissible everyday operating load.

Industrial WLL – 5,600kg

For industrial applications, Wichard specifies:

WLL: 5,600kg

Wichard states that WLL applies only to industrial applications, such as lifting. The manufacturer applies a safety factor of five against the Breaking Load:

28,000kg ÷ 5 = 5,600kg WLL.

The three important load figures are therefore:

1.011kg Weight

The Wichard #11248 weighs:

1.011kg

Considering its 28,000kg Breaking Load, the #11248 provides an impressive strength-to-weight ratio for a heavy-duty 20mm stainless-steel shackle.

For performance-oriented marine hardware, achieving very high mechanical strength without unnecessary mass remains an important advantage.

Bow Shackle Ω vs D Shackle

The choice between a Bow Shackle and D Shackle depends on the geometry and requirements of the connection.

A D shackle has a narrower body, creating a more compact connection point.

The Bow / Ω Shackle has a wider, rounded body, providing additional internal room.

For the #11248, Wichard specifically identifies two important advantages of this geometry: ample connection space and the possibility of attaching several lines or cables.

If the installation requires both exceptional strength and additional connection space, the Ω profile offers a significant practical advantage.

Designed for High-Load Applications

Wichard specifically recommends the #11248 for applications requiring high loads.

Depending on the design, load and geometry of the installation, this makes it particularly relevant for applications such as:

• Heavy-duty sailing hardware
• Yacht hardware
• Rigging applications
• Performance sailing
• High-load attachment points
• Professional marine installations
• Connections requiring additional internal space
• Applications involving several compatible lines or cables

Correct sizing remains essential. The actual load, direction of loading, connection geometry and specifications of the other components should always be considered.

CE Marking

The Wichard #11248 is CE marked.

For industrial applications, Wichard specifies a 5,600kg WLL, using a safety factor of five against its 28,000kg Breaking Load.

This provides clearly defined technical load ratings for professional users selecting hardware for the intended application.

Important – Not for Mooring

Despite its exceptional 28-tonne Breaking Load, Wichard explicitly states that the #11248:

Must not be used for mooring applications.

This is an important distinction. A very high Breaking Load does not automatically make a shackle suitable for every marine application or every type of dynamic loading.
