Grade 70 chain is also known as transport chain, tie down chain, binder chain, and trucker's chain. This standard link, high quality chain is manufactured in a high-strength, low-alloy carbon steel. It is most commonly used as tie down on trailers, but is also used for towing, logging, safety, and oil rigging applications. The standard link chain can be easily identified by its gold or yellow chromate finish, which is recognized industry wide as the color for Grade 70. Each chain is embossed for easy identification.

All our Grade 70 chain products are heat-treated and strength-tested for superior quality and meet both NACM and ASTM requirements. Grade 70 chain should never be used for overhead liftings.

Be sure to check out our Grade 80, 100, or 120 tie down chain assembly options as well.
