Tongue Flat is 2.25" wide and 3.00" long. Steel gauge 1/4 inch. There is a 3/4 inch gap between the shaft around the hinge pin and the hinge pin. I drilled a hole in the flat area to get my hitch pin. I used 2 U clamps to connect this loop to the rear handle of my Artic Cat sled (this should work with any sled). This bow is perfect for my needs!.
