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.
