Technical Specifications
Master Links are typically forged or welded from high-strength alloy steel, ensuring durability and load-bearing capacity. The working load limit (WLL) varies depending on the size and material of the link. For example, a 1/2" Master Link may have a WLL of 0.5 tons, while a 2" Master Link can support up to 150 tons . The ultimate load is generally 4 to 5 times the WLL, providing a safety margin for operational use .
The dimensions of Master Links are standardized according to international standards such as EN 1677 and ISO 16797. These standards ensure that Master Links are compatible with various lifting systems and can be used in different industries, including marine, construction, and logistics . The internal dimensions, such as length and width, are also specified to ensure proper fit and function when assembling slings or lifting gear .

Applications
Master Links are essential in both lifting and lashing operations. In lifting applications, they connect multiple legs of a sling to a central point, distributing the load evenly. In lashing applications, they secure cargo or equipment to prevent movement during transport. For example, a 13mm Master Link is commonly used in maritime lashing systems, where it must withstand significant tension and environmental stress .
Master Links are also used in conjunction with other rigging components, such as clevis hooks, flexible connectors, and tensioning devices. These combinations ensure that lifting operations are both safe and efficient. For instance, a 1-1/4" Master Link with a welded VRG connector is often used in heavy-duty lifting applications, where it provides a secure and reliable connection .
