Sub assemblies like this are really best-suited for non-adjustable chain slings--meaning the sub-links are small and can only accommodate two couplers per link. You do not have enough space to make an old-fashioned "ADOS"
type of chain sling. The upshot is that these link will work with inline adjusters (such as Pewag's XK shorteners), and because they are compact they do not add a bunch of unnecessary weight to your chain assembly. They can also be used with wire rope slings, synthetic slings and rope assemblies. Made from Grade 100 steel, proof-tested, heat-treated with full product traceability. Safety factor of 4:1.
