Nilight Straight Trailer Coupler with Security Latch&Chain

Nilight straight trailer coupler securely connects 2-inch hitch balls to 3-inch tongues with a 3,500 lb capacity and an integrated latch pin and chain for double protection.

This heavy-duty trailer tongue coupler from Nilight combines a robust zinc-finished die-cut steel body with a fast-action locking system designed for both bolted and welded mounting. Built to resist rust and to simplify hookup, the unit fits 2-inch trailer balls and is made for 3-inch channel tongues, offering dependable towing for station wagons, trucks, and a wide range of trailers. The included latch pin and chain add redundancy so the connection remains secure during transit.

How does this coupler make hitching faster and safer?

The Nilight coupler uses an easy-lock mechanism that streamlines attachment and removal while keeping the ball firmly seated. A positive latch engagement reduces the chance of accidental disengagement, and the supplemental pin and chain deliver added peace of mind on the road.

• Quick-release latch for fast hookup and unhooking
• Latch pin and chain prevent unintended opening
• Visible seating of the ball for confident installation

What load and size specifications should I expect?

This straight coupler is rated for up to 3,500 pounds gross trailer weight and is explicitly made to accept standard 2-inch hitch balls. It is engineered to slide onto a 3-inch channel tongue and provides consistent load support when installed correctly.

• Rated capacity: 3,500 lbs gross trailer weight
• Ball size compatibility: 2-inch hitch balls
• Tongue/channel fit: compatible with 3-inch trailer tongues

How durable is the construction and finish?

Nilight manufactures this coupler from thick die-cut steel and applies a zinc coating to guard against corrosion. The robust build stands up to frequent use and exposure to the elements, while the finish slows rusting and abrasion for longer service life.

• Die-cut steel body for structural strength
• Zinc finish for corrosion and rust resistance
• Designed for repeated bolting or welding without compromised integrity

What mounting options are supported for installation?

The coupler supports both bolted and welded installations, letting you choose the mounting method that matches your trailer fabrication or maintenance preferences. Bolt-on installation enables easier replacement, while welding gives a permanent, heavy-duty bond.

• Bolted installation for reversible mounting and easy service
• Welded installation for a permanent, high-strength attachment
• Pre-cut holes and clean edges for straightforward fitting

Who is this product for? Nilight's 2-inch straight trailer coupler is intended for trailer owners and fabricators who need a reliable, easy-to-use hitch connection rated around mid-range towing loads. It suits owners of station wagons, light trucks, utility trailers, small campers, and anyone replacing a worn coupler or upgrading to a zinc-coated, latch-pin-secured design. Choose bolting if you expect to service or swap components frequently; choose welding for a permanent high-strength mount. Always verify vehicle and trailer ratings, install per manufacturer guidance, and inspect the latch pin and chain before each trip for safe towing.
