Professional-Grade Marine Rigging Hardware

Engineered for extreme maritime environments, this AISI 316 Stainless Steel Square Eye Plate with captive ring offers unmatched durability and corrosion resistance. Unlike standard 304 steel, our 316 alloy contains Molybdenum, providing superior protection against pitting and crevice corrosion in saltwater applications.

  • Marine-Grade Durability: Constructed from high-tensile AISI 316 stainless steel for maximum longevity in harsh weather.
  • Precision Welded: Features deep-penetration, seamless welding on the closed-loop ring to ensure structural integrity under dynamic loads.
  • Mirror-Polished Finish: Electropolished to a mirror finish for high reflectivity and enhanced resistance to surface contaminants.
  • Versatile Installation: The 4-hole countersunk plate design allows for flush-mount installation on fiberglass, wood, or metal surfaces.
  • Multi-Purpose Utility: Ideal for boat deck rigging, shade sail tensioning, architectural cable systems, and high-load gym suspension anchors.

Each unit includes premium 316SS mounting screws and expansion anchors for immediate, secure deployment.

Frequently Asked Questions

Will this eye plate rust if installed permanently on a boat used in saltwater?
No. Unlike 304-grade hardware, this eye plate is forged from AISI 316 stainless steel, which contains Molybdenum to specifically inhibit pitting and chloride corrosion commonly found in marine environments.
Is the ring welded shut or is there a seam that could open under heavy tension?
The ring features a seamless, deep-penetration weld construction. This 'closed-loop' design ensures the ring cannot deform or open even under the maximum working load limits of heavy-duty rigging applications.
Can I use this for overhead suspension of gym equipment or heavy punching bags?
Yes. The 8mm variant is specifically designed for high dynamic loads. When installed with the included expansion anchors into a structural substrate, it provides a secure, vibration-resistant anchor point for suspension training and heavy loads.

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.

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.
