Please measure your trailer beam width before purchasing to ensure a snug fit and secure bolting or welding. **Q: Does it come with the mounting bolts and safety pin?** A: 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. **Q: Can I weld this coupler instead of using bolts?** A: 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. **Q: Is the zinc plating sufficient for use on a boat trailer in salt water?** A: 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. **Q: How do I adjust the tightness of the coupler on the ball?** A: 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. ## Frequently Bought Together - 2" X 3" Trailer Coupler 3500 lbs, Towing Boat Straight Coupler - Torin 1000 lbs Trailer Jack with Wheel, Heavy Duty Swivel Boat Trailer Jack Single Whee, 10" Lift, Bolt-on Trailer Tongue Jack for RV Boat ATR39001B, Silver - MAXXHAUL 70205 Trailer Light Kit - 12V All LED, Left and Right Waterproof Submersible for Trailers, Boat Trailer Truck Marine Camper RV Snowmobile, Red --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/89781038-2-x-3-trailer-coupler-3500-lbs-towing-boat-straight](https://www.desertcart.sc/products/89781038-2-x-3-trailer-coupler-3500-lbs-towing-boat-straight) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-10-17*
