With a working load limit of 4,700 Lbs. / 2,131 Kgs., Cargo Control Store’s heat-treated carbon steel 5/16-inch x 550-foot Grade 70 Bulk Chain exceeds your expectations of strength and gives you an effective tie down method that you can rely on. Not only is our gold dichromate chain strong, but it’s also zinc plated to prevent corrosion, so it will remain durable longer than an untreated chain. This chain assembly is most commonly used as a tie-down on flatbed trailers but is also used for towing, logging, safety, and oil rigging applications.

This convenient chain assembly comes pre-cut with the forged alloy steel Clevis Grab Hooks already installed, so it is ready to be used for the toughest jobs. The hooks are sturdy enough to slip onto your anchor point and stay there throughout transit to keep your load steady and secure.

Our 5/16-inch x 550-foot Grade 70 Bulk Chain is engineered to meet the National Association of Chain Manufacturers’ requirements. The Grab Hooks are embossed with Grade 70, size, and country of origin. This chain must not be used for overhead lifting.
