A master link is a vital chain component used to fasten slings to chain loads, they are widely used in lifting sets for offshore containers. These large oblong links are constructed from quenched and tempered alloy steel and they are proof tested to 2.5 times the working load limit. Certification is provided with each master link. These master links are made with a large width and length to allow the use of thimbles for larger wire ropes that tend to be utilised in brindle configurations. Master links are available in various diameters to suit different sizes of chain and wire rope.
