Identify CURT Trailer Safety Chains and Cable Pairs
An existing trailer safety assembly may be a single S-hook chain or one cable from a matched pair. CURT uses different part numbers for its lengths, coating and rated capacities. This comparison helps identify a missing or damaged assembly and explains why a minimum breaking force is not the same number as a working-load limit.
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.
Inspect the existing towing safety equipment
- Identify the original stamped manufacturer number and whether it is a single chain or a pair of coated cables.
- Check the actual length, hook shape and any markings that indicate manufacturer ratings; do not infer a working-load rating from breaking-force data.
- Check that links are not elongated and cable strands are not broken or exposed through coating.
- Compare the listed pack quantity with the actual item offered. A used single cable does not necessarily constitute the original two-piece set.
- Replace assemblies with damaged hooks or unknown ratings only with properly rated equipment suited to the trailer. UsedRVParts viewing and pickup in Kelowna are by appointment.
Identify the exact CURT safety assembly
Review the individual product listing for its condition and included quantity.
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.
