C.E. Smith Safety Chain Set, Class IV

The C.E. Smith Safety Chain Set, Class IV is a heavy-duty trailer safety solution designed to keep your trailer secured to the tow vehicle in the event of coupler failure or accidental separation. This Class IV safety chain set delivers 7,600 lb towing capacity and comes as a complete pair, making it suitable for mid-size to large trailers used in recreational boating, utility hauling, and equipment transport. The zinc-plated, proof-coil construction resists corrosion while maintaining tensile strength under sustained load and vibration.

Each chain measures 24 inches in length and features heat-treated S-hooks rated for the full 7,600 lb capacity. The 8/0 chain gauge and proof-coil design ensure durability during repeated towing cycles without kinking or deformation. Zinc plating provides reliable corrosion resistance in both freshwater and moderate salt-air environments. Proper installation is critical—the open hook end must be attached up through the mounting hole rather than down, which prevents accidental disengagement during transit and protects against hook bounce-out on rough terrain.

This safety chain set is intended for boat trailer owners, utility trailer operators, and anyone regularly towing equipment where redundant safety systems are required. Whether you're transporting a center-console fishing boat, enclosed cargo trailer, or landscaping equipment, Class IV chains serve as a critical failsafe. Compliance with safety chain requirements varies by state and load weight—verify local regulations before choosing your chain class. Weigh your trailer and cargo to confirm that Class IV capacity meets your specific towing application.

C.E. Smith is a well-established manufacturer of trailer hardware and towing components, and this safety chain set represents standard-duty equipment suitable for general recreational and light-commercial towing. The 24-inch length accommodates most modern tow hitch and trailer eye configurations without excessive slack.
