Nilight Straight Trailer Coupler with Security Latch&Chain

The Nilight straight trailer coupler secures 2-inch hitch balls and 2-inch trailer tongues with a 3,500 lb capacity, featuring a safety latch pin and chain for dependable towing connections.

This heavy-duty coupler is designed for everyday towing needs on station wagons, trucks, and utility trailers. Constructed from thick die-cut steel with a zinc finish, it resists rust and stands up to road conditions. The unit supports both bolted and welded mounting methods and includes an easy-lock mechanism for fast attachment and removal.

How does this coupler make hitching faster and safer?

The Nilight coupler uses an easy-lock system that simplifies connecting and disconnecting the trailer from the tow vehicle. A spring-loaded latch secures over the 2-inch ball, while a latch pin and attached safety chain provide secondary protection to prevent accidental disengagement. This combination reduces the chance of trailer separation while on the road.

• Quick-release latch for single-handed coupling
• Latch pin plus chain prevents accidental unlatching
• Fits standard 2-inch hitch balls and tongues
• 3,500 lb rated capacity for light- to medium-duty towing

Will this coupler resist corrosion and road wear?

The coupler is fabricated from thick die-cut steel and finished with a protective zinc coating to slow oxidation and surface rust. The durable coating and robust steel construction help maintain structural integrity despite exposure to moisture, salt, and gravel. Regular inspection and light maintenance extend service life.

• Zinc-plated surface for corrosion resistance
• Die-cut steel body for consistent strength and fit
• Designed for everyday road conditions and seasonal storage

How do I install this coupler on my trailer?

This Nilight coupler supports both bolted and welded installation to match your trailer setup and fabrication capabilities. For a removable or replaceable mount, use the bolting holes and grade hardware; for a permanent attachment, weld in place following proper trailer-welding practices. Always torque bolts to specifications and test latch operation before towing.

• Two installation methods: bolted for replaceability, welded for permanence
• Pre-cut mounting holes align with 2-inch channel tongues
• Test latch and pin engagement after installation and periodically

What load and fit should I expect from this coupler?

The Nilight coupler is rated for a gross trailer load up to 3,500 pounds and is sized to accept 2-inch hitch balls and 2-inch trailer tongues. It is suitable for small utility trailers, campers, and lightweight cargo trailers used with passenger vehicles and light trucks. Match the coupler rating to your trailer’s Gross Trailer Weight (GTW) and ensure the hitch ball and mount are rated equally or higher.

Who is this for: The Nilight straight trailer coupler is ideal for owners of small to medium trailers who need a reliable, easy-to-use connection for daily hauling or weekend trips. It suits DIY trailer builders, fleet owners who want a replaceable bolted option, and anyone who prefers the permanence of a welded mount. If you tow with a station wagon, pickup, or compact truck and use a 2-inch ball setup, this coupler provides a secure, corrosion-resistant link between vehicle and trailer.
