Designed for use with marine and utility trailers, Fulton brand tongue jacks are time-tested and application-proven. Our bolt-on versions include all necessary mounting hardware. For weld-on applications, we offer two styles of mounts for both 1/2" and 3/8" pull pin models. The Fulton brand bolt-thru swivel mounts (U.S. PAT. 6,302,381) use 3-D formed heavy-gauge steel stampings and a proprietary bushing material for a mount with minimal deflection and Z-Maximum support. All mounts fit up to a 3" x 5" trailer frame. With more than 100 years of impeccable performance, the Fulton line of trailer jacks, winches, and couplers has become the industry standard for light and medium-duty trailering. Suited for all environments, Fulton performs best when the weather is at its worst. When innovative design is combined with quality and value, the result is a brand that is the obvious choice for recreational and marine applications everywhere.
