Chain sling 100 DOG

2-pointsteel

Product Overview
Grade 100 DOG chain sling is a double-leg lifting assembly manufactured from quenched and tempered Grade 100 alloy steel chain and components. The sling is fitted with a Grade 100 oblong master link on the top and two Grade 100 grab hooks on the bottom, providing adjustable chain lengths and secure two-point lifting for overhead applications. Compared with Grade 80 slings, the Grade 100 design offers approximately 25% higher Working Load Limit for the same chain size. Each sling is permanently identified with a serial number, chain size, grade, exact sling length, and Working Load Limit to ensure complete product traceability.
