Engineered for Extreme Marine Environments

Maximize your rigging efficiency with the Airow Marine 316 Stainless Steel Twisted Shackle. Forged from premium marine-grade alloy, this shackle features a specialized 90-degree twisted body designed to provide perfect perpendicular alignment, preventing binding in halyards, anchors, and chains.

  • Superior Material Integrity: Contains Molybdenum for elite resistance to chloride-induced pitting and crevice corrosion in saltwater.
  • Forged vs. Cast: Unlike brittle cast hardware, our solid forged construction offers vastly superior tensile strength and fatigue resistance.
  • Mirror-Polished Finish: High-reflectivity surface minimizes drag and prevents dirt accumulation while providing a sleek aesthetic.
  • Universal Utility: Optimized for yacht rigging, heavy-duty gym setups, yoga hammocks, and industrial trailer safety.

Frequently Asked Questions

Will this twisted shackle rust if left in salt water permanently?
No. This shackle is forged from genuine 316 Marine Grade Stainless Steel, which includes Molybdenum. This specific alloy is engineered to resist chloride pitting and corrosion even in continuous saltwater immersion, unlike standard 304 stainless.
What is the advantage of a 'twisted' shackle body over a standard D-shackle?
The 90-degree twist allows for a perpendicular connection. This is critical for rigging applications where you need lines or chains to hang straight without the binding or twisting that occurs when using two standard shackles together.
Can I trust this shackle for heavy overhead gym equipment?
Yes. Our visual forensics confirm a solid forged construction, which provides significantly higher tensile strength and structural integrity than cheaper cast alternatives. The 8mm variant features a breaking strength of 300kg, making it ideal for gym and industrial applications.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.

Currently, AirowMarine is continuously optimizing our packaging solutions: we maximize the reduction of single-use plastics in our packaging and shipping processes, using recyclable paper-based cushioning materials whenever possible. Our products are built to power your voyage, while our packaging is designed to protect the purity of the blue sea.
