【NACM-Compliant】​Made of high-grade Grade 80 chain material, with a yellow zinc chromate coating on the surface (corrosion-resistant and moisture-proof, suitable for humid marine/dock environments), and clear embossed markings on the chain body; fully complies with NACM (National Association of Chain Manufacturers) standards, applicable to marine/dock operation scenarios; when used for securing truck trailer loads, it can smoothly pass roadside safety inspections to ensure compliant transportation. 【High-Load Capacity】​Heavy-duty chain with 7,100 LBS capacity, 3/8 inch chain diameter combined with an overall heat treatment process (enhances tensile strength and wear resistance), whose performance far exceeds the basic requirements of industrial safety chains; the chain body has embossed capacity certification codes for quick verification of load-bearing parameters, suitable for construction equipment towing scenarios; Never exceed the Safe Working Load (SWL)! to avoid safety risks. 【High-Strength Structural Design】​The chain specification is 3/8 inch × 10 feet (the length is suitable for medium and small-sized heavy-load fixing needs), and it comes standard with 2 G70 clevis grab hooks (with a reasonable opening and stable grip, facilitating quick hooking); the chain links adopt advanced full-penetration welding technology, with no false welds and anti-fracture performance, which can reliably fix and fasten heavy objects to improve operational stability. 【Safety-Oriented Design】​Specifically designed for bundling and securing heavy-duty cargo, with a Safe Working Load (SWL) of 7,100 pounds and an extremely high safety factor (can cope with sudden stress during transportation and reduce the risk of fracture); typical applications include flatbed truck cargo transportation and vehicle towing, while also suitable for industrial equipment fixing, agricultural heavy machinery transfer, professional towing and other scenarios; relying on NACM certification, it can completely avoid the risk of non-compliant operations and ensure operational compliance. 【Multi-Industrial Heavy-Load Solution】​Can be used as a tow chain with hooks for machinery transportation and dock cargo loading/unloading operations; widely serves scenarios such as factories (heavy equipment movement), ports (container/large cargo fixing), and heavy-duty operation users (engineering/agricultural towing), realizing "one chain for multiple uses" and adapting to heavy-load transportation and fixing needs across multiple industries.
