NBJINGYI's straight trailer coupler connects 2" trailer tongues to 2" hitch balls with a secure latch and 3500 lb rated capacity.

This rugged coupler is designed for utility trailers, ATV haulers, small cargo trailers and other 2" straight-tongue applications. Built from thick die-cut steel with a durable black finish, it offers a simple latch operation, pin-ready safety holes and corrosion resistance for regular towing use. The coupler is sized for a 2" channel width and fits standard 2" diameter trailer balls, making it a drop-in replacement or an upgrade for most small trailers.

How does this coupler secure to a 2" trailer tongue?

The coupler slides into a 2" straight tongue channel and clamps down over a 2" trailer ball using an easy-lock latch. When closed, the latch locks over the ball neck and the unit provides holes to accept a safety pin or coupler lock for added theft and uncoupling protection.

• Fits 2" channel width straight tongues.
• Accepts standard 2" trailer balls.
• Latch provides positive engagement over the ball neck.
• Integrated holes for safety pin or padlock.

What load and durability can I expect from this 3500 lb coupler?

The 3500 lb rating indicates the coupler is intended for trailers with a maximum gross trailer weight within that capacity. Its construction from thick, die-cut steel and a protective black finish helps resist wear and light corrosion from road exposure, providing reliable service when maintained.

• Rated for up to 3500 pounds gross trailer weight.
• Heavy-gauge steel body for structural strength.
• Protective black coating reduces surface rust.
• Regular inspection and lubrication extend service life.

How easy is the latch operation and safety pin installation?

The coupler uses an easy-lock latching mechanism that can be operated by hand without tools. Once the latch is seated over the ball, align the built-in holes and insert a safety pin or compatible coupler lock to prevent accidental uncoupling or unauthorized removal.

• Simple hand-operated latch for quick hitching.
• Visible alignment for pin insertion.
• Works with standard cotter pins or small coupler locks.
• Minimal force required—suitable for frequent use.

Will this coupler resist rust and road wear?

The unit is manufactured from thick die-cut steel and finished in a durable black coating intended to slow rust and protect against everyday abrasion. While the coating improves longevity, occasional cleaning, touch-up paint, and lubrication are recommended for long-term protection in corrosive environments.

• Black protective finish reduces surface corrosion.
• Thick steel construction stands up to impact and strain.
• Periodic maintenance keeps moving parts smooth.
• Touch-up paint helps in salty or wet climates.
