This heavy-duty trailer jack is designed for boat and utility trailers that require a compact, corrosion-resistant support with easy cranking and smooth mobility. The unit mounts to a 3"–4" trailer tongue, adjusts from 10½" to 20½" height, and features a zinc finish for improved resistance to rust and water exposure. Its swing-back design folds the jack against the tongue, keeping it clear during towing and storage.
The swing-back swivel lets you quickly move the jack out of the way without removing it, reducing time and hassle before you hit the road. Folding the tube mount flush with the tongue improves ground clearance and prevents damage while towing.
This model is rated for loads up to 2,000 pounds (1 ton), making it suitable for many small boats, utility trailers, and campers. It welds to pipe mounts sized for 3" to 4" trailer tongues and offers a variable lift to match hitching heights.
The jack receives a zinc finish that helps shield the steel from corrosion commonly encountered on boat trailers and in coastal areas. For extended service life, regular rinsing after saltwater exposure and occasional lubrication of the screw and swivel components will keep it operating smoothly.
The cast crank handle lets you raise and lower the trailer quickly with minimal effort, and the jack wheel improves mobility while positioning the trailer at the hitch or on a ramp. The user manual included covers installation, welding guidelines, and safe operation tips.
Who is this for: The TCE ATR39003U is aimed at trailer owners who want a permanently mounted jack that’s easy to stow, corrosion-resistant, and capable of handling small- to mid-size loads. Boat owners, small cargo trailers and light-duty campers will benefit from the swing-back convenience, adjustable lift range, and the mobility provided by the jack wheel. If you need a weld-on solution with a clean folded profile and dependable 2,000 lb capacity, this jack meets those requirements with straightforward installation and minimal upkeep.
