Will this coupler fit my 2-inch wide square trailer tongue? Yes, this coupler is specifically designed for a 2-inch wide channel or square tongue. Please measure your trailer beam width before purchasing to ensure a snug fit and secure bolting or welding. Does it come with the mounting bolts and safety pin? This package includes the coupler assembly only. You will need 2 grade-5 bolts (typically 3" x 7/16") and a safety pin or lock for the latch. This allows you to choose the hardware that best fits your specific trailer frame. Can I weld this coupler instead of using bolts? Absolutely. While many users prefer bolting for easy replacement, the heavy-duty steel construction is suitable for welding to provide a more permanent and rigid connection to your trailer tongue. Is the zinc plating sufficient for use on a boat trailer in salt water? Yes, the zinc finish is designed to provide excellent corrosion resistance. However, for maximum longevity in saltwater environments, we recommend rinsing the coupler with fresh water after each use. How do I adjust the tightness of the coupler on the ball? There is an adjustment nut located under the latch. You can tighten or loosen it to ensure the coupler fits snugly on your 2-inch ball without excess play, ensuring a quiet and safe towing experience. ## Features - 3,500 LBS HEAVY-DUTY RATING Rated for a gross trailer weight (GTW) of 3,500 lbs, this 2" coupler is engineered for mid-sized loads. It provides robust support for 19 ft bow riders, sailboat trailers, and equipment haulers, offering a significant capacity upgrade for your towing setup. - 2" BALL & 3" CHANNEL FIT Specifically designed to fit a standard 2" diameter hitch ball and a 3" wide straight trailer tongue. This wider channel specification is ideal for reinforced trailer frames commonly found on larger boat trailers and utility haulers. - QUICK-RELEASE LATCHING SYSTEM The integrated easy-lock latching mechanism ensures efficient attachment and detachment. The spring-loaded lever provides a firm grip on the hitch ball, maintaining a secure connection through marinas, farm fields, or job sites. - SAFETY LOCK PRE-DRILLED HOLES Features integrated holes specifically sized to accept a safety pin or coupler lock (sold separately). This design provides a dedicated spot for secondary security to help prevent accidental uncoupling during highway travel or while parked. - ZINC-PLATED SURFACE FINISH Constructed from thick, die-cut steel with a durable zinc-plated metallic finish. This surface treatment is designed for outdoor durability and maintains its functional integrity even with exposure to water and salt during seasonal use. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07BDFM4VG | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #2,048 in Automotive (See Top 100 in Automotive) #1 in Trailer Coupler Parts | | Brand Name | NBJINGYI | | Compatible With Vehicle Type | Marine-Personal-Craft, Trailer | | Customer Reviews | 4.7 4.7 out of 5 stars (380) 4.7 out of 5 stars | | Finish Type | Zinc Plated | | Item Type Name | 2" Straight Trailer Coupler | | Manufacturer | JY | | Manufacturer Part Number | 1BJY-TC-06 | | Manufacturer Warranty Description | one year | | Material Type | Alloy Steel | | Maximum Towing Capacity | 3500 pounds | | Model Number | JG-X7IU-N2S0 | | Pull Force | 3500 pounds | | Unit Count | 1 Count | | Upc | 729043886999 | ## Product Details - **Brand:** NBJINGYI - **Vehicle Service Type:** Marine-Personal-Craft, Trailer - **Material:** Alloy Steel - **Finish Type:** Powder Coated - **Automotive Fit Type:** Universal Fit ## Images ![NBJINGYI Straight Trailer Coupler for 2" Ball and 3" Channel,3500 lbs | 3500 lbs Gross Weight Capacity, Zinc-Plated Steel for Boat, Utility and Equipment Trailers - Image 1](https://m.media-amazon.com/images/I/51UFotME6dL.jpg) ![NBJINGYI Straight Trailer Coupler for 2" Ball and 3" Channel,3500 lbs | 3500 lbs Gross Weight Capacity, Zinc-Plated Steel for Boat, Utility and Equipment Trailers - Image 2](https://m.media-amazon.com/images/I/71lIxJOisCL.jpg) ![NBJINGYI Straight Trailer Coupler for 2" Ball and 3" Channel,3500 lbs | 3500 lbs Gross Weight Capacity, Zinc-Plated Steel for Boat, Utility and Equipment Trailers - Image 3](https://m.media-amazon.com/images/I/81UXSv8cW9L.jpg) ![NBJINGYI Straight Trailer Coupler for 2" Ball and 3" Channel,3500 lbs | 3500 lbs Gross Weight Capacity, Zinc-Plated Steel for Boat, Utility and Equipment Trailers - Image 4](https://m.media-amazon.com/images/I/819ikvNc2ML.jpg) ![NBJINGYI Straight Trailer Coupler for 2" Ball and 3" Channel,3500 lbs | 3500 lbs Gross Weight Capacity, Zinc-Plated Steel for Boat, Utility and Equipment Trailers - Image 5](https://m.media-amazon.com/images/I/71TmPvTCeTL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this coupler fit a 2-inch hitch ball?** A: No, this model is designed for a 1-7/8 inch trailer ball and a 2-inch wide straight tongue.
