Nilight Straight Trailer Coupler — 2-Inch Hitch Ball / 2-Inch Channel, 3,500 lb Capacity, Zinc Finish

The Nilight Straight Trailer Coupler is a tough, zinc‑finished steel coupler engineered to attach 2‑inch trailer tongues to 2‑inch hitch balls with a 3,500 lb capacity.

This straight coupler is built to simplify hooking and securing small trailers, utility carts, and light-duty equipment while resisting rust. Its die‑cut steel body, easy-lock latch and included pin-and-chain safeguard provide a reliable connection at a competitive price. You get both bolted and welded installation options so the coupler fits a range of trailer builds and repair needs.

How secure is the Nilight coupler when towing?

The coupler combines a positive latch mechanism with a locking pin and safety chain to reduce the chance of accidental uncoupling. The zinc coating protects the metal from corrosion, helping maintain that secure fit over time.

• 3,500 lb gross towing capacity rating for light trailers
• Latch with included pin and chain for double security
• Zinc finish to resist rust and preserve clamping force
• Die‑cut steel construction for consistent fit and strength

Will this fit my trailer and hitch hardware?

This coupler is sized specifically for a 2‑inch hitch ball and a 2‑inch trailer tongue (channel width). It’s intended for straight coupler applications where the tongue inserts flush into the coupler body.

• Designed for 2‑inch diameter hitch balls
• Fits 2‑inch trailer tongues/channels
• Compatible with standard straight coupler mounting arrangements
• Available for bolted or welded attachment methods

How easy is installation and daily use?

The Nilight coupler is made for quick on‑off operation with a simple latch system that releases and secures rapidly. Installers can choose bolting for simpler aftermarket replacement or welding for a permanent factory‑style mount.

• Quick‑release latch for fast hookup and detachment
• Two installation choices: bolt‑on or welded
• Pre‑formed die‑cut holes for straightforward bolting (when applicable)
• Included pin and chain make everyday safety checks simpler

What materials and finish protect this coupler from wear?

Constructed from thick die‑cut steel, the coupler is surface‑treated with a zinc finish that helps prevent oxidation and surface degradation from road salt and moisture. That treatment extends service life and helps maintain mechanical tolerances.

• Thick die‑cut steel body for structural durability
• Zinc plating for corrosion resistance
• Robust latch hardware designed for repeated use
• Finish and materials chosen to reduce maintenance needs

Who this is for: The Nilight Straight Trailer Coupler is aimed at DIY trailer owners, small fleet operators, landscapers, and hobbyists who need a reliable, economical coupler for light‑duty towing tasks. Choose bolted installation if you expect to replace or upgrade the coupler later, or opt for welding for a permanent mount. This product suits trailers and equipment rated up to 3,500 pounds that use a 2‑inch ball and matching 2‑inch tongue channel.
