Shackles
3 products available
Shackles are fundamental connectors used in a wide range of rigging, lifting, and securing systems. These U-shaped metal links are closed by a pin, forming a secure attachment point for chains, ropes, and slings. They are indispensable in industrial machinery, marine rigging, and material handling operations. Compel supplies a focused selection of rigging shackles for professional trade and industry use.
Our inventory includes common types such as bow shackles and dee shackles, also known as d shackles. We provide components made from materials like 304 stainless steel, suitable for applications requiring corrosion resistance. With clear technical specifications listed for every item, you can confidently source the correct screw pin shackles or other fasteners for your specific industrial application.
Choosing Your Shackle Type: Bow vs. Dee
The first decision is the shape of the shackle body. The two primary types are bow shackles and dee shackles.
Bow shackles have a larger, rounded 'O' shape. This design allows them to handle loads from multiple angles, making them suitable for connecting multi-leg slings to a single hook. Dee shackles, or d shackles, have a narrower 'D' shape, similar to a loop of chain. They are designed for straight, in-line pulling and should not be side-loaded.
Pin and Fastener Selection
The pin is the component that closes the shackle. Screw pin shackles are common for applications that require frequent connection and disconnection. The pin threads directly into the shackle body, allowing for quick and easy removal.
Other fasteners, such as spring-gate hooks and quick links, are available for light-duty securing and connecting chains. These are not intended for the heavy or dynamic loads that a standard lifting shackle is designed to bear. Always confirm the fastener type matches your application's security and load requirements.
Material: 304 Stainless Steel vs. Iron
Material choice depends entirely on the operating environment. Our shackles are available in specified materials to meet distinct industrial needs.
304 stainless steel provides very good corrosion resistance. This makes it a standard choice for marine rigging, food processing, and outdoor applications where exposure to moisture is constant. Iron is a base material whose performance depends on its finish. For corrosion resistance, an iron shackle must have a protective coating, such as galvanization. Always check the product listing to confirm the exact material and any protective coatings.
Buying guide
Choosing Shackles
- How do I determine the correct shackle size for my load?
- Shackle size is determined by its Working Load Limit (WLL), which must exceed the maximum force in your application. The listed size, such as M10, refers to the diameter of the shackle body stock. Always consult the product's datasheet to find its specific WLL, as this is the most important factor for safety.
- What is the functional difference between bow shackles and dee shackles?
- Bow shackles have a large, rounded shape to accommodate loads from multiple directions, making them ideal for use with multi-leg slings. Dee shackles (d shackles) have a narrower profile for in-line loads only and are not designed for side loading.
- Which material is appropriate for outdoor or marine use?
- 304 stainless steel is the proper choice for marine, washdown, or outdoor environments due to its high corrosion resistance. Standard iron shackles will rust quickly unless they have a specified protective coating like hot-dip galvanization.
- Are these rigging shackles rated for overhead lifting?
- Shackles used for overhead lifting must have a manufacturer-certified Working Load Limit (WLL). While our category includes industrial-grade rigging shackles, you must verify the WLL and any compliance standards on the individual product datasheet before using it for any lifting operation.
- What does the 'M' size on a screw pin shackle indicate?
- The 'M' designation, such as M8, refers to the nominal metric diameter of the steel body. The number in the designation corresponds to the diameter in millimeters. This dimension helps you match the shackle to the chain link or sling eye it will be connecting.
