Oblong Links—For Lifting
Also known as master and sling links, a large inner diameter provides room to attach multiple connectors or legs on a sling. Use these links in general lifting applications. All meet strict ASME safety standards for lifting.
Links for Grade 120 chain are the strongest we offer. They are approximately 20% stronger than links for Grade 100 chain and about 35% stronger than links for Grade 80 chain. Links for Grade 100 chain are approximately 20% stronger than links for Grade 80 chain. Links for Grade 63 chain are approximately 60% as strong as links for Grade 80 chain.
Powder-coated alloy steel links have mild corrosion resistance. Stainless steel links better resist corrosion compared to steel links.
Links with a flat have a spot that's thinner than the rest of the link, so you can slip on connectors that otherwise wouldn't fit. The flat doesn't affect the capacity of the link.
Forged links offer greater strength than welded links.
Note: Capacities listed are for vertical lifting only. As the angle changes from vertical, the amount of weight the link can lift is significantly reduced.

Oblong Link Assemblies—For Lifting
Providing better load distribution and alignment than single oblong links, these reduce wear in three- and four-leg slings. All meet strict ASME safety standards for lifting.
Links for Grade 120 chain are the strongest we offer. They are approximately 20% stronger than links for Grade 100 chain and 35% stronger than links for Grade 80 chain.
Links for Grade 100 chain are approximately 20% stronger than links for Grade 80 chain. They have a maximum lifting angle of 60°.
Links for Grade 80 chain have a maximum lifting angle of 60°.

Oblong Links—Not for Lifting
Smaller than lifting oblong links, these links provide room for snaps, carabiners, and other non-lifting connectors. Use them to secure loads with ropes or chains.
Galvanized steel links have a thick coating for corrosion resistance.
