6400 marine jack · 1,000 lb capacity · 10 in lift
One 6-in wheel; bolt-on swivel, sidewind
Review matching productAn older trailer jack may have lost its label, making several Dutton-Lainson swivel models look alike. Compare the wheel layout, crank position, mounting bracket and lift travel before choosing a replacement. An apparently similar 1,500 lb jack may belong to a different series or have a different caster arrangement.
