Marine Shackles

In the maritime and industrial sectors, the integrity of your rigging hardware is non-negotiable. Our comprehensive range of marine shackles is engineered to deliver unparalleled safety, strength, and corrosion resistance for the most demanding applications. Whether you are securing cargo, assembling lifting gear, or mooring vessels, our shackles provide the reliable connection you need.

We offer a diverse selection of styles, materials, and sizes to meet global standards, including JIS, US Type, and BS3032. From small-boat rigging to large-scale industrial lifting, you can find the perfect heavy-duty shackle for your operation.

Types of Marine Shackles Available

1. Stainless Steel JIS Type Dee Shackles (Chain Shackle)
Designed for applications requiring a direct in-line pull, our JIS Type Dee shackles feature a narrow, symmetrical design ideal for use with chains and in systems where space is limited.

Material: Premium AISI 304 or AISI 316 stainless steel for excellent corrosion resistance in marine environments.
Process: Manufactured using a precision forging process, ensuring a robust grain structure and a high load capacity for reliable performance.
Finish: Bright, passivated finish for enhanced durability and a professional look.

JIS Type Dee Shackle Specifications (AISI304/AISI316)

Size (M)	C (mm)	H (mm)	W (mm)	D (mm)	Breaking Load (KG)	Weight (KG)
M4	4	15	8	8	500	0.008
M6	6	21	12	12	1100	0.025
M20	19	61	37	40	10000	0.728
M32	31	114	64	64	32000	3.63
(Full size range from M4 to M32 available upon request.)

2. Stainless Steel US Type Bow Shackles (Anchor Shackle)
The US Type Bow shackle is distinguished by its larger, rounded “bow” shape. This design allows it to handle multi-directional loads, making it the ideal choice for anchor shackle applications, lifting slings, and general rigging where the load may come from an angle.

Material: High-grade AISI 304 or AISI 316 stainless steel.
Superior Design: The shackle pin is larger in diameter than the shackle body, providing an even heavier load capacity and increased shear strength compared to standard designs.
Versatility: Perfect for connecting multiple sling legs or components in a lifting assembly.

US Type Bow Shackle Specifications (Imperial Sizes)

Size (inch)	Pin Dia D (inch)	W (inch)	H (inch)	WLL (tons)	Weight (lbs)
3/16	0.19	0.38	0.88	1/3	0.05
3/8	0.38	0.66	1.44	1	0.31
3/4	0.81	1.25	2.81	4-3/4	2.25
1-1/2	1.62	2.38	5.75	17	17.2
(Full imperial range from 3/16″ to 2-1/2″ available.)

3. Large Bow Shackles BS3032 (Carbon Steel)
For the heaviest industrial lifting tasks, our Large Bow Shackles BS3032 are the ultimate choice. Manufactured to the rigorous British Standard, these shackles are built for extreme loads in ports, shipyards, power plants, and heavy construction projects.

Standard: Complies with BS3032 specifications.
Material: High-strength 45 carbon steel, chosen for its excellent tensile properties.
Process: Produced using the free forging process, which aligns the metal grain to withstand immense stress. The surface is kept in its original color with a protective coating.
Safety Factor: The MB proof load is tested to 2 times the Working Load Limit (WLL) , ensuring a significant margin of safety.
Applications: Ideal for port operations, power generation, shipbuilding, oil fields, and construction sites.
