Tonque Jacks - rust resistant

I have replaced my trailer jack twice now due to rust. I noticed my buddy’s pathfinder had a Dutton Lainson on it. His trailer lives outside and the coast and mine stays with me in the upstate most of the time. His seemed to still be in good condition, no visible corrosion. I did not get the model number but their website says they use some kind of zinc coating.

Does anyone sell these locally? Any other recommendations?

I bought a good Fulton from Northern Tool about 3 years ago. Has a few spots of minor rust but noting a wire brush won’t take care of.

wesco trailors in cayce,sc has the best price on trailor jacks without a doubt. bought one from them three weeks ago for my 19’seapro. cost me less than $25 . that was half the price of an average one that i saw at northern tool. give them a call. jeremy is easy to work with and very helpful.
