Tnyeobae 35" Trailer Safety Chains 2-Pack — Grade 70 Heavy-Duty, 24,000 lb Break Strength, Yellow Zinc

Tnyeobae’s 35" Grade 70 safety chain 2-pack is a heavy-duty backup towing system rated for a 24,000 lb break strength (8,000 lb working load per chain) with yellow zinc corrosion protection and forged 3/8" clevis snap hooks.

When towing a boat, RV, dump trailer or construction equipment you need a secondary connection you can trust. These Tnyeobae chains are built from Grade 70 alloy steel and finished in a yellow zinc plating to resist salt and road chemicals. The 35-inch length is sized for a criss-cross under the coupler and the included clevis snap hooks have spring-loaded latches for fast, secure attachment.

How does this chain protect my trailer if the hitch fails?

The chain serves as a redundant connection between trailer and tow vehicle. If the primary hitch connection gives way, these Grade 70 chains limit separation and help keep the trailer aligned for controlled stopping and recovery.

• 24,000 lb break strength across the pair for high-resistance backup
• 8,000 lb working load per chain to meet common towing standards
• Forged clevis snap hooks with spring latches to stay locked under load
• 35" length designed for proper criss-cross routing beneath the coupler

Will these chains withstand marine or winter use?

Yes — the yellow zinc plating provides stronger corrosion resistance than basic galvanizing, helping prevent rust from road salt and saltwater spray. That makes them well-suited for boat launches and snowy driving conditions.

• Professional yellow zinc finish resists salt and moisture better than plain zinc
• Plating extends service life in coastal and winter environments
• Suitable for repeated launches and exposure to de-icing chemicals

Are the hooks easy and safe to attach?

The chains come with 3/8" forged clevis snap hooks that use a spring-loaded latch to prevent accidental release. They allow one-handed connection while maintaining a secure lock during vibration and rough terrain.

• Forged construction for durability under heavy loads
• Spring-loaded latch keeps the hook closed during movement
• Quick-connect design for fast setup and teardown at the hitch

Do these meet legal or commercial safety requirements?

The two-chain set is configured and sized for cross-chain routing, which is a common requirement in many jurisdictions and for professional haulers. The Grade 70 alloy steel rating and specified working load make it appropriate for heavy-duty applications.

• 35" length allows criss-cross setup under the hitch as typically required
• Grade 70 classification and rated WLL provide clear load metrics for inspections
• Pack of two supplies both sides for compliant safety-chain installations

Who is this for: These chains are aimed at boat owners, RV drivers, dump-trailer operators, and tradespeople who need a contractor-grade, budget-conscious safety solution. Installers and fleet managers who require clear load ratings and corrosion-resistant components will appreciate the combination of Grade 70 strength, forged hooks, and yellow zinc protection.
