This U Bolt can have a variety of uses in the trailer world. However, we most likely see it mounting the trailers leaf springs to a 2 inch square trailer axle. These 2" Square tubed axles are most common on boat trailers, but can also be seen on utility trailers as well. You would see two of these U Bolts per side, mounting through a 5 Hole Leaf Spring Plate. Check the length of mounting u bolt required to make sure this size is right for your set up.
