YOMILINK 5000 lb A-Frame Trailer Jack — 15" Lift, Adjustable Drop Leg, Galvanized Steel

YOMILINK's 5000 lb A-frame trailer jack is a heavy-duty, adjustable drop-leg jack that lifts A-frame trailers 15" with a 23.2"–45.6" height range for safer hitching and stable parking.

This trailer jack combines a 5,000-pound rated lift, five-step height adjustment, and a removable drop leg in a galvanized carbon-steel body for corrosion resistance and dependable performance.
