How to Install Weld-On Folding Trailer Coupler on Trailer Frame

Question:

Fulton Fold-Away Coupler Hinge Kit for 3inch x 3inch Tongue - Bolt On - Up to 5,000 lbs Item # FHDPB330301 Regarding the above. Is this the right product for my 1989 Road Runner 17ft boat trailer. The box tube of the tongue piece measures 2.5 inches by 2.5 inches. Many thanks.

The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 fits only a 3 x 3-inch trailer tongue. We do have other sizes of folding coupler, all are shown on the linked page, but none fits a 2-1/2- x 2-1/2-inch trailer tongue.

To use one of these on your trailer you will need to use a 3 x 3 weld-on type coupler like # FHDPW330300 and have the qualified welder who will install it also install steel spacer plates on the trailer tongue before welding the coupler into place.
