A boat trailer jack that uses a snap ring works differently than one that is a bolt-on, like yours, because the mounting bracket for a bolt-on jack and snap-ring jack will be different.

Because you have a Fulton 1,200 lb bolt-on jack, I assume your mounting bracket that is welded on accepts a bolt, like part # P9012-00. If this is the case you are going to want a compatible, bolt-on jack, which is the Fulton Bolt-Thru Swivel Marine Jack # FXP10W0301. This jack has a 1,200 lb capacity, offers 10" of lift and has a 600 hour salt spray rating.

Your photos did not come through; however, take a look at the Fulton Bolt-Thru Swivel Marine Jack w/ Caster # FXP10, which might work for you. It fits 3" x 5" trailer frames and if you check out the accompanying photo it will show you the dimensions of the mounting bracket. You can use this to compare it to yours to see if it is a fit.
