Professional Grade 70 Transport Chains – Heavy-Duty Tie-Down Series

DOT/FMCSA Approved Carbon Steel Chains for Flatbed Hauling, Logging, and Heavy Machinery

OVERVIEW

Ensure maximum load security and regulatory compliance with our Professional Grade 70 Transport Chains. Engineered specifically for the rigorous demands of the heavy hauling industry, these high-tensile tie-downs are forged from heat-treated carbon steel, providing exceptional strength-to-weight ratios. Finished in a high-visibility gold chromate to resist rust and environmental corrosion, every chain is stamped at regular intervals to meet strict DOT and FMCSA inspection requirements. Available in versatile pre-cut lengths with clevis grab hooks, or as continuous-length bulk pails for custom fleet outfitting, this series is the definitive standard for towing, logging, and heavy machinery transport.

SYSTEM HIGHLIGHTS

• DOT & FMCSA Compliant: Every chain is permanently stamped every foot with the Grade 70 identifier, ensuring immediate traceable load rating compliance during highway weigh station inspections.

• Heat-Treated Carbon Steel: Forged and heat-treated to withstand extreme tension, abrasive wear, and high-impact shock loads without snapping or deforming.

• Gold Chromate Defense Finish: The premium dichromate plating provides a highly visible yellow/gold finish that actively resists oxidation, road salt, and job site moisture.

• Multi-Gauge Versatility: The matrix spans from standard 7.9 mm (5/16") to massive 15.9 mm (5/8") thicknesses, allowing operators to match chain strength to their specific Working Load Limit (WLL) requirements.

• Bulk & Pre-Cut Configurations: Choose between ready-to-deploy 6.1 m to 9.1 m (20 ft to 30 ft) assemblies or high-volume continuous 18.3 m to 27.4 m (60 ft to 90 ft) bulk pails for shop fabrication.
