Do you have a question about this Trailer Coupler?

• Should I Use a Bolt On or a Weld on Fold Away Coupler On my 17 Foot Lowe Aluminum Boat Trailer
  
• I more or less agree with you. The Fulton Fold-Away Hinge Kit for 3 x 3 inch Trailer Tongue - Weld-On, item # FHDPW330300, is a cleaner look and if you got a bad weld job you would not have a safe setup. I have done some welding, I am in no way a professional weldor, and in my limited experience a good weld will not fail before the steel it is welded to will fail. If you like the clean look of the weld on I would have a certified weldor perform the operation. If you take the trailer to him the

• Installation Tips When Installing Fold-Away Coupler Hinge Kit, Part # FHDPB330301
  
• Any drill bit designed for drilling through metal will work, although tungsten carbide bits are the best (although pricey). Here are a few tips for drilling through metal. Start with a small bit, drill a pilot hole and switch to an intermediate sized bit, followed by the final diameter. Drill at a slow speed, while applying steady pressure. I suppose you could use a hacksaw to cut your trailer tongue, but it would take quite some time and many, many blades. Your best bet would be to use a rec

• What Angle does the Fulton Fold-Away Coupler Open Up To
  
• The couplers will swing 180 degrees. Depending on how long the tongue is and the shape of the trailer the coupler may hit the trailer frame before it opens up to 180 degrees. I installed one of these on a small boat trailer this summer. The tongue was 36 inches long so we cut it at 18 inches and installed the Fulton Fold-Way. It doubled back on itself when folded out and we gained 18 inches of garage space.

• Weight Capacity of Fulton Fold-Away Coupler Hinge Part # FHDPB330301
  
• I have spoken with one of our contacts at Fulton, who tell me that exceeding that 5000 lb capacity is NOT recommended. The Fold-Away kit is designed for a static weight of up to 5000 lbs, but that figure can be momentarily exceeded each time you hit a bump or a pothole. I would recommend taking your boat to a truck scale to verify the actual weight of the boat and trailer. If you find that you are under the 5000 lb figure, the Fulton Fold-Away kit would work very well for you.
