NBJINGYI 2" Straight Trailer Coupler for 2" Ball & 2" Channel — 3,500 lb Zinc-Plated, Quick-Release Latch

The NBJINGYI 2" Straight Trailer Coupler is a zinc-plated, 3,500 lb-rated hitch coupler designed to securely attach trailers with a standard 2" ball and 2" channel tongue.

This straight coupler from NBJINGYI delivers a balance of strength and everyday convenience for boaters, landscapers, and utility trailer owners. Engineered from die-cut steel with a corrosion-resistant zinc finish, the unit fits a 2" diameter hitch ball and a 2" wide trailer tongue. It features a spring-loaded quick-release latch that secures the ball, plus pre-drilled holes to accept a safety pin or coupler lock for added peace of mind when towing or parking.

How strong is this coupler and what loads can it handle?

The coupler carries a 3,500 lb gross trailer weight (GTW) rating, suitable for mid-size trailers such as bow riders, small sailboat trailers, and equipment haulers. This rating reflects the structural capacity for combined trailer and cargo weight within manufacturer limits. Always confirm your vehicle and trailer weight limits before use.

• Rated GTW: 3,500 lbs for typical mid-size applications
• Designed for 2" ball and 2" channel tongue compatibility
• Suitable for boats, utility trailers, and small equipment trailers

How does the quick-release latch improve hookup and safety?

The integrated spring-loaded latch simplifies coupling and uncoupling: push the lever to open, seat the ball, then release to lock. The mechanism gives a firm grip on the hitch ball to reduce play while towing. For added security, the coupler includes pre-drilled holes that accept a safety pin or dedicated coupler lock (sold separately).

• Spring-loaded lever for fast, one-hand operation
• Firm locking action to minimize movement and noise on the road
• Pre-drilled holes sized for safety pins or locks to prevent accidental uncoupling

Is the coupler durable for outdoor and marine use?

Constructed from die-cut steel and finished with zinc plating, the coupler resists rust and corrosion from road salts and water exposure. The metallic finish prolongs service life and keeps moving parts functioning in seasonal conditions. Regular inspection and light maintenance, such as cleaning and lubrication, will further extend performance.

• Die-cut steel construction for robust structural strength
• Zinc-plated surface resists corrosion from water and salt
• Low-maintenance design: clean and lubricate pivot points periodically

Will this fit my trailer and what installation steps are needed?

The coupler is intended for standard 2" diameter hitch balls and 2" wide straight trailer tongues; verify your tongue width and ball size before purchase. Mounting requires aligning the coupler to the tongue and securing with appropriate bolts or welding per trailer specifications. Use the pre-drilled safety-hole for a locking pin after mounting and coupling.

• Fits 2" hitch ball and 2" straight trailer channel tongues
• Mount by bolting or welding to trailer tongue following torque specifications
• Use safety pin or coupler lock in pre-drilled hole after coupling

Who is this for: The NBJINGYI 2" Straight Trailer Coupler is aimed at owners of mid-size trailers who need a reliable, corrosion-resistant hitching solution. It suits boat owners, landscapers, tradespeople, and weekend DIYers who tow 3,500 lbs or less and want a quick-release latch plus a built-in provision for secondary safety. If you operate trailers with a 2" ball and 2" channel tongue and expect regular outdoor or seasonal exposure, this coupler provides a practical upgrade in strength and usability.
