HWH Chain - High Test 40/43
HWH 10312731 G43 High Test Mooring Chain 5/8" x 150' Long Link Hot Dip Galvanized
When it comes to securing recreational vehicles, trailers, and specialty equipment, HWH brings the same commitment to reliability and durability that has made them a trusted name in the RV and trailer industry for decades. HWH's Chain - High Test 40/43 product line delivers the strength and dependability needed for critical towing, tie-down, and safety applications where failure is not an option.
Understanding High Test 40/43 Chain
High test chain, available in both Grade 40 and Grade 43 classifications, represents a significant step up from standard proof coil chain in terms of strength-to-weight ratio. These chains are engineered to handle demanding applications including vehicle recovery, load securement, and towing safety chains required by DOT regulations. The "high test" designation refers to the chain's superior tensile strength and its ability to withstand dynamic loads encountered during transport and recovery operations.
HWH's Approach to Chain Quality
As a manufacturer with extensive experience in the RV and trailer market, HWH understands the critical nature of chain components in transportation safety systems. Their high test 40/43 chain products are designed to complement the rigorous standards that professionals and enthusiasts expect when securing valuable equipment. The chain construction focuses on consistent link geometry, proper heat treatment, and precise manufacturing tolerances that ensure reliable performance under stress.
Applications for Grade 40 and Grade 43 Chain
HWH's high test chain serves multiple purposes in the recreational vehicle and trailer ecosystem. These chains are commonly specified for:
- Safety chains connecting trailers to tow vehicles, meeting federal towing requirements
- Load securement systems for equipment, ATVs, and cargo
- Recovery operations where higher strength ratings are essential
- Tie-down applications requiring superior holding power in compact sizes
- Logging, construction, and agricultural equipment restraint
Choosing the Right Grade
The distinction between Grade 40 and Grade 43 chain matters for specific applications. Grade 43 offers approximately 15% greater working load limit compared to Grade 40 of the same size, making it the preferred choice for maximum load capacity in weight-sensitive applications. Both grades feature the same link dimensions, but the metallurgical differences result in varying performance characteristics. Understanding your vehicle's gross weight, tongue weight, and safety chain requirements helps determine which grade specification best suits your towing configuration.
Integration with HWH Systems
For those already using HWH hydraulic leveling systems, slide-outs, or other trailer components, adding HWH high test chain to your safety and securement setup ensures consistent quality across your entire rig. The chain's reliability pairs naturally with the precision engineering that HWH applies to their hydraulic and mechanical systems, creating a comprehensive approach to vehicle safety and performance.
