Stainless Steel D-Ring Shackle — Heavy Duty Tow Recovery & Marine Mooring Connector

A shackle is only as reliable as its material and closure. This D-ring shackle is constructed from marine-grade stainless steel with a screw-pin closure — providing corrosion resistance, high tensile strength, and a secure, rattle-free connection for tow recovery, boat mooring, rigging, and load-securing applications.

Technical Specifications

Key Features

• Marine-grade stainless steel: Resists rust, saltwater corrosion, and UV degradation — maintains strength and appearance in harsh marine and outdoor environments
• Screw-pin closure: Threaded pin screws securely into the shackle body — prevents accidental opening under load while allowing tool-free release when needed
• D-ring geometry: The straight back of the D-ring distributes load evenly across the pin — more efficient load transfer than round bow shackles for in-line pulling applications
• Universal compatibility: Accepts rope, chain, wire cable, and webbing straps — suitable for a wide range of rigging and recovery configurations
• Polished finish: Smooth surface prevents chafing on rope and webbing during dynamic load applications

Common Applications

• Vehicle tow recovery (winch line to recovery point connection)
• Boat mooring line to cleat or anchor connection
• Ship rigging and block-and-tackle systems
• Anchor chain to anchor shackle connection
• Load securing on trailers and flatbed trucks
• Rope-to-chain transition in anchor rode systems

Frequently Asked Questions

Q: What is the working load limit (WLL) of this shackle?
A: Please refer to the product images for the specific WLL rating of the size selected. Always apply a safety factor of at least 4:1 (use a shackle rated for 4× the maximum expected load) for dynamic or shock-load applications such as vehicle recovery.

Q: Should I use a mousing wire on the screw pin for critical applications?
A: Yes. For applications where vibration could cause the screw pin to back out (rigging, towing, anchor systems), thread a mousing wire through the pin hole and around the shackle body to prevent rotation. This is standard marine rigging practice.

Q: Is this shackle suitable for overhead lifting?
A: Only if the shackle is specifically rated and certified for overhead lifting (EN 13889 or equivalent). General-purpose shackles should not be used for overhead lifting without verified certification. Check the product markings for lifting certification.
