Stainless-Steel Shackles
When corrosion is the main concern, stainless steel shackles are the way to go. While not as strong as steel, they perform well in and around saltwater and other reactive environments. Stainless-steel is the best at resisting corrosion, however it could rust over time, so we strongly recommend maintaining and cleaning this shackle type periodically.

Soft shackles and steel shackles each have unique advantages depending on the application. Soft shackles are made from high-strength synthetic fibers, making them lightweight and easy to handle. They are ideal for applications where weight is a concern, such as in sailing or outdoor adventure sports. Steel shackles, on the other hand, provide superior durability and strength, making them better suited for heavy industrial applications and lifting heavy loads. Steel shackles, especially those made from stainless steel or galvanized steel, are preferred in environments where corrosion resistance is crucial.
The weight capacity of a 1-inch shackle depends on its material and grade. Typically, a 1-inch steel shackle can hold between 8.5 tons to 13.5 tons depending on whether it is a Grade 6 or Grade 8 shackle. It's important to check the specific load rating for the shackle type you are using. Always refer to the manufacturer's specifications and ensure compliance with safety standards to avoid overloading.
When using shackles, avoid side-loading unless the shackle is explicitly designed for such use, as it can significantly reduce the shackle's load-bearing capacity. Never use a damaged or deformed shackle and ensure the pin is properly secured. Overloading, mismatching sizes and types, and exposing shackles to corrosive substances without proper corrosion resistance are also practices to avoid.
D shackles, also known as chain shackles, should not be side loaded due to their straight shape and narrower loop compared to bow or anchor shackles. Side loading on D shackles can cause them to twist or bend, compromising the integrity of the load. For applications requiring side-load handling, bow shackles are more appropriate as their rounded shape allows for distribution of the load more evenly.
304 stainless steel contains 18% chromium and 8% nickel, making it highly resistant to corrosion and widely used for kitchenware and piping. 316 stainless steel, also known as marine grade stainless, includes 2% molybdenum which enhances its resistance to chloride exposure and makes it ideal for marine environments. While both types are durable, 316 is preferred for harsher conditions, particularly where salinity or chemicals are present.
