Check listed part and availabilityIdentify CURT Trailer Safety Chains & Cables by MPN and Rating
Replacing worn trailer safety hardware? Before buying a chain or cable set, identify the exact CURT number, attachment style, overall reach and minimum break-force specification. Two assemblies can look alike but differ in their rated strength, hook size or packaged quantity. This guide helps identify five commonly listed CURT parts without relying on appearance alone.
Identify the part before replacing it
- Look for the CURT part number. A package label, invoice or other part record can help distinguish 80030 from packaged 80031 and the cable pairs from individual chains.
- Count the supplied pieces. CURT 80010, 80030 and 80031 each identify one complete chain with two S-hooks. CURT 80151 and 80176 identify a set of two safety cables.
- Inspect the ends. The chain assemblies use S-hooks; the coiled cable sets use safety-latch snap hooks. Make sure their opening and attachment method suit the trailer and tow vehicle.
- Compare specifications, not just the shape. Chain-link diameter, cable minimum break force and total length are key to identifying a correct replacement.
CURT chain and cable identification chart
| MPN | Supplied item | Size | Ends | Minimum break force |
|---|---|---|---|---|
| 80010 | Individual Grade 30 steel chain | 48 in chain; 3/16 in links | Two 3/8 in S-hooks | 2,000 lb |
| 80030 | Individual zinc-plated chain | 48 in chain; 1/4 in links | Two 7/16 in S-hooks | 5,000 lb |
| 80031 | Packaged individual chain | 48 in chain; 1/4 in links | Two 7/16 in S-hooks | 5,000 lb |
| 80151 | Two coiled, vinyl-coated cables | 42 in cable assemblies | Snap hooks | 5,000 lb |
| 80176 | Two coiled, vinyl-coated cables | 42 in cable assemblies | Snap hooks | 7,500 lb |
Important distinction: The values above are CURT's minimum break-force specifications, not general working-load limits or a substitute for confirming the trailer's gross vehicle weight rating. The manufacturer's guidance says each chain or cable assembly must meet or exceed the trailer's gross weight. Inspect the attachment hardware and local towing requirements too.
What makes these parts different?
80010: The smaller 3/16-inch chain has a 2,000 lb minimum break force. 80030 and 80031: These use 1/4-inch Grade 30 chain with a 5,000 lb minimum break force; 80031 is the packaged listing. 80151 and 80176: Both come as pairs of coiled, vinyl-coated cables; the 80176 is specified at 7,500 lb rather than 5,000 lb.
Do not confuse a cable's retail headline dimension with the manufacturer-listed assembly length. CURT describes 80151 as a 44½-inch safety-cable product but separately lists two 42-inch cable assemblies. For 80176, the headline says 44 inches and its product specification lists 42 inches.
Check any secondhand hardware carefully
Used chains and cables can be difficult to evaluate if the label is missing. Look for stretched or bent links, deformed hooks, damaged latches, broken cable strands, coating damage and corrosion. Replace questionable components rather than assuming they retain their original rating.
