NBJINGYI 2" Trailer Coupler for 2" Tongue — 3,500 lb Capacity, Lever Latch, Black Finish

NBJINGYI Straight Trailer Coupler secures a 2" ball to trailers with a 2" tongue and supports up to 3,500 lbs with a durable latch and locking holes.

This straight coupler from NBJINGYI is built for everyday towing tasks where a compact, reliable connection is essential. Designed to mate with standard 2" trailer balls and 2" wide tongues, it provides a straightforward locking mechanism, corrosion-resistant finish, and pass-through holes for a safety pin or coupler lock. The unit is intended for trailers, utility carts, lawn equipment trailers, and other light-duty tow setups that require a simple, robust attachment.

How does this coupler attach to my trailer and hitch ball?

The coupler mounts over a 2" wide straight trailer tongue and clamps down onto a matching 2" hitch ball. A lever-style latch captures the ball and secures the connection, while additional holes let you insert a safety pin or padlock for extra security. Installation is straightforward and typically bolts to the tongue plate using standard fasteners.

• Fits 2" wide straight tongues and 2" hitch balls.
• Lever latch locks the ball in place for reliable towing.
• Holes accept a safety pin or aftermarket coupler lock.
• Mounts with common bolts through the coupler base plate.

What towing capacity and materials should I expect?

This model is rated for a gross towing load up to 3,500 pounds, appropriate for light to medium trailers and small utility loads. The body is fabricated from die-cut steel with a protective black finish to resist rust and wear during regular use. While robust for its class, it is not intended for heavy-duty or commercial towing beyond its rated capacity.

• Rated capacity: 3,500 lbs (suitable for many small trailers).
• Constructed from thick die-cut steel for strength.
• Black protective coating improves corrosion resistance.
• Not designed for loads exceeding the rated limit.

How simple is operation and maintenance?

The coupler uses an easy-lock latching system that lets you secure or release the hitch ball quickly, reducing time spent hooking up. Periodic inspection, basic lubrication of moving parts, and checking fasteners will keep the mechanism operating smoothly. The black coated steel helps slow corrosion, but touch-up paint and routine cleaning extend life in wet or salty environments.

• Quick-release latch for fast hookup and removal.
• Minimal routine maintenance: lubricate and inspect.
• Corrosion-resistant finish reduces upkeep frequency.
• Safety-pin hole permits secondary locking for added security.

Will this coupler fit different trailer setups or require modifications?

It is made to pair with straight tongues that are 2" wide and standard 2" hitch balls, so most common small trailers will be compatible without modification. If your tongue width or ball size differs, an adapter or different coupler size will be required. For welded or custom tongues, confirm hole spacing and plate thickness before installation to ensure secure mounting.

• Direct fit for standard 2" tongues and 2" balls.
• Adapters needed for nonstandard tongue widths or ball sizes.
• Check base plate hole spacing for bolt alignment.
• May require reinforcement on thin or damaged tongue plates.
