Because the Grade 120 chain is often reserved for the toughest heavy-duty jobs, our Grade 120 Chain Assemblies are more than capable of handling those and so much more. These chains are engineered using this high-quality square link chain so that they are able to work with a higher strength-to-weight ratio, making them about 20-percent stronger than Grade 100 chains and 50-percent stronger than Grade 80 chains. The Cradle Grab Hook Chains, which are available in 3/8” by 10’ and 20’ sizes and in 1/2" by 10’ sizes, are some of the strongest chain assemblies that you could ever need. They can handle a working load limit between 10,600 lbs. and 17,900 lbs. so that they can easily handle the heavy-duty jobs with greater ease and efficiency. The cradle grab hooks are manufactured to provide solid support as they are designed with deep throats that allow them to easily slide right into the anchoring points in order to establish a reliable connection. They can also be used to hook directly onto the links of a chain. When it comes to strength, you know that this is the right chain for the job.
