Curt Certified S-Hook

CURT certified S-hooks are the easy, reliable way to connect your safety chains from your trailer to your tow vehicle. They feature a heat-treated steel construction to ensure long-lasting wear resistance, and they come with a zinc-plated finish to outlast the elements. This particular S-hook has a 7/16" diameter and offers a gross trailer weight capacity of 5,000 lbs. It also features a spring-loaded safety latch. Similar to a quick link, the safety latch allows for a safety chain connection that won't come loose from vehicle vibrations or jarring on uneven terrain. For added safety, this S-hook is tested and certified to meet SAE J684 standards. Remember, when attaching safety chains, the chains should be cross underneath the trailer coupler, and each hook and chain must be rated to meet or exceed the gross weight of the trailer
