CURT Trailer Safety Chains vs Cables: Lengths & Ratings
Trailer safety chains and cables are the secondary connection between a trailer and the tow vehicle if the coupler separates. CURT offers S-hook chain assemblies and coated snap-hook cable pairs with different lengths and stated ratings. Choose these components according to the trailer's requirements and the precise manufacturer's rating—not by appearance alone.
Chain assemblies or coated cable pairs?
CURT 80010, 80030 and 80031
These are individual zinc-finished safety-chain products with S-hook ends, listed at 48 inches overall. The 80010 manufacturer data explicitly gives a 2,000 lb minimum breaking force. The other two listings state a 5,000 lb gross-load capacity.
CURT 80151 and 80176
Both are supplied as pairs of black coated safety cables with snap hooks. The 80151 is listed at 44½ inches and 5,000 lb; the 80176 is 42 inches and 7,500 lb. Do not compare the coating and hook style without checking the required rating.
CURT chains and cables comparison
| CURT MPN | Design | Length | Package | Ends | Published rating |
|---|---|---|---|---|---|
| 80010 | Grade 30 chain | 48 in overall | Single | Two S-hooks | 2,000 lb minimum breaking force |
| 80030 | Trailer safety chain | 48 in | Single | S-hooks | 5,000 lb listed gross-load capacity |
| 80031 | Trailer safety chain | 48 in | Single | S-hooks | 5,000 lb listed gross-load capacity |
| 80151 | Safety cable | 44½ in | Pair | Snap hooks | 5,000 lb listed load rating |
| 80176 | Safety cable | 42 in | Pair | Snap hooks | 7,500 lb listed load rating |
Rating distinction: The 2,000 lb value for CURT 80010 is a manufacturer-specified minimum breaking force. It must not be represented as an independent working-load limit or automatically compared with differently specified load-capacity figures.
Before selecting a secondary connection
- Check the trailer manufacturer's instructions and applicable towing requirements for how many safety assemblies are needed and the minimum approved rating for each.
- Confirm whether your application requires chain assemblies or cables; both must have correctly rated attachment hardware and a suitable tow-vehicle anchor point.
- Match the overall reach with room for turning while keeping components off the ground, avoiding tight pulls and dragging.
- Verify the rated hooks or snap hooks fully engage the approved points. Never attach them to a removable ball mount or other unapproved part.
- Inspect every assembly for stretching, damaged links, bent hooks, frayed cable or corrosion before towing. Follow the trailer maker's instructions on crossing and routing.

Coupler latch pins have a different purpose
To retain a coupler latch or jack component, use the CURT coupler safety-pin size and chain guide. A small latch pin does not replace a rated trailer safety-chain or safety-cable assembly.
