NBJINGYI 2" Class III A-Frame Trailer Coupler — 7,000 lb Forged Steel, Black E-Coat, Quick-Lock Latch

NBJINGYI’s 2" Class III A-frame coupler is a forged-steel, 7,000 lb-capacity trailer hitch head with a quick-lock latch and durable black E-coat finish.

Designed as a direct-fit replacement for standard 50-degree A-frame tongues, this coupler combines heavy-gauge construction with a positive-locking mechanism to make hitching faster and more secure. It’s made for utility, equipment, and contractor trailers that need dependable connection strength without complex installation steps.

How much weight can this coupler safely support?

The NBJINGYI coupler is rated to handle a gross trailer weight (GTW) of 7,000 lbs when properly installed on an appropriately matched trailer. The forged steel head and Class III specification provide the structural capacity to tow heavier loads within this rating.

• 7,000 lb gross trailer weight (GTW) rating.
• Forged steel head designed for heavy-duty load transfer.
• Meets SAE Class III compliance standards for similar-rated hitches.

How does the quick-lock latch system improve hookup and safety?

The quick-lock mechanism gives a positive, snug fit on a standard 2" trailer ball, reducing time spent aligning and securing the trailer. Its design keeps the ball seated firmly while you fasten safety chains and complete checks before departure.

• Positive-locking latch for secure engagement.
• Simple open/close action speeds hitching and unhitching.
• Works with standard 2" tow balls for broad compatibility.

What makes the NBJINGYI finish better for outdoor use?

This coupler is coated with a black electrophoretic coating (E-coat) to resist rust, moisture, and abrasion from frequent use. The finish helps the latch continue to operate smoothly by shielding mating surfaces against corrosion and UV wear.

• High-performance black E-coat to resist corrosion and chips.
• Protects moving parts for consistent mechanical performance.
• Durable surface suitable for outdoor and worksite exposure.

Will this coupler fit my trailer tongue and how is it installed?

The coupler is built for a standard 50-degree A-frame tongue and is intended to be welded directly onto the trailer tongue as a replacement unit. Proper welding and alignment are important to maintain the rated capacity and safe towing geometry.

• Designed for standard 50-degree A-frame configuration.
• Weld-on installation — professional welding recommended for rated capacity.
• Direct replacement for many utility and equipment trailers.

Who is this for: The NBJINGYI 2" Class III A-frame coupler fits contractors, landscapers, fleet owners, and DIY trailer owners who need a robust, reliable hitch head for hauling heavy loads. If you require a straightforward weld-on replacement with a quick-lock latch and a corrosion-resistant finish, this coupler delivers commercial-grade strength and long-term service life.
