Question:
How does this weld-on? It looks like a bolt-on to me. Im trying to replace the Fulton jacks weve been using, that were: weld-on, side-wind, wheeled -preferably 8, at least 10inch lift. Thoughts?

Hey Jon, welcome back. The adapter plate included with the Ultimate Trailer Jack item # UJ44FR can be welded directly to your trailer's frame. You can also use the included hardware and brackets to bolt it to your trailer's frame.
The Ultimate Trailer Jack item # UJ44FR is a 1,500 lbs capacity jack with a 27-1/2" total lift. It is zinc plated for corrosion resistance and includes a 5-3/4" wheel. This would be a great replacement for your older Fulton Jack.

This is a surprisingly heavy jack for a 1,500 lb rating. For most applications, the bolt on (really clamp on) option should work well and install in minutes. I also like the fact that wheel swivels easily on hard surfaces.
