Flexible 7x19 Stainless Steel Wire can be used for a range of systems on dinghies and yachts. It is commonly used throughout the yachting world, and you can now configure and purchase the flexible wires you need on our website. Here at Martin Leaning Masts & Rigging we use KOS 7x19 stainless steel wire, here's why it is a great choice. In our opinion it's the world's best wire and our terminals are from premium world recognised brands, and all rigging is professionally terminated with meticulous care.

The 7×19 stainless steel wire rope construction is the most flexible of the multi-strand wire ropes and is used for a wide range of applications where the wire needs to bend around corners. Often used as winch cables and for guardrails and balustrade applications where the curves, corners and angles are required.

Flexible 7x19 Wire and KOS: Strength and Flexibility for Marine Rigging

Wire rope plays a crucial role in marine rigging, offering strength, durability, and adaptability for various sailing applications. Among the different wire constructions, 7x19 stainless steel wire is favored for its flexibility and high fatigue resistance. When paired with KOS wire, known for its superior quality, sailors get a reliable solution for demanding rigging needs.

What Is 7x19 Wire Rope?

The 7x19 construction consists of seven strands, each made up of 19 individual wires, creating a rope that is strong yet highly flexible. This design allows for easy bending and movement, making it an ideal choice for applications where wire needs to wrap around pulleys, blocks, or other fittings.

Key Benefits of 7x19 Wire:

• Exceptional Flexibility – Unlike stiffer wire constructions (e.g., 1x19), 7x19 bends easily without kinking.

• High Fatigue Resistance – Handles repeated loading cycles without losing strength.

• Reliable Performance – Retains structural integrity even under tension and marine exposure.

• Ease of Handling – Ideal for applications requiring frequent movement.

Why Choose KOS Wire for 7x19 Rigging?

KOS wire is marine-grade stainless steel, ensuring long-lasting durability in harsh environments. Here’s why sailors prefer KOS wire for their 7x19 rigging needs:

1. Excellent Corrosion Resistance

Saltwater exposure is a constant challenge for marine rigging. KOS wire resists rust and corrosion, making it ideal for long-term use without degradation.

2. Reliable Strength and Load Capacity

While 7x19 wire is more flexible than other types, it still offers impressive load-bearing capability, ensuring secure rigging for dinghies, lifelines, and control cables.

3. Smooth Handling and Compatibility

KOS wire integrates seamlessly with swaged fittings, thimbles, and tensioners, providing a secure and durable rigging system that can withstand continuous use.

4. Versatility Across Sailing Applications

7x19 KOS wire is widely used in:

• Lifelines – Soft and flexible enough for comfortable handrails.

• Control Cables – Ideal for applications requiring frequent adjustments.

• Running Rigging – Used where wire flexibility is beneficial, such as furling systems.

Maintenance and Longevity

To maximize 7x19 KOS wire lifespan, regular inspection is necessary:

• Check for signs of wear or fraying in wire strands.

• Clean with freshwater to prevent salt buildup after sailing.

• Inspect end fittings and terminals for corrosion.

• Ensure correct tension to prevent excess slack or overloading.

With proper care, KOS wire in a 7x19 construction provides years of reliable service, keeping your rigging safe and efficient.

Conclusion

For sailors needing flexibility, strength, and corrosion resistance, 7x19 KOS wire is an excellent choice. Whether used for lifelines, control cables, or specialized rigging, its durability ensures smooth operation and reliability on the water. Choosing high-quality stainless steel wire like KOS ensures long-term performance and safety in marine environments.
