Dutton-Lainson DLX-SW Swivel Trailer Jack, 1700 lb Capacity, Bolt-On Wheel Jack, Part 22339

The Dutton-Lainson DLX-SW (part number 22339) is a bolt-on swivel trailer jack built for boat and utility trailers with square tongues up to 3 in x 4 in. Rated for a 1,700 lb capacity, it gives trailer owners an easy way to level and support the tongue at the ramp, in storage, or during hitching. The jack swivels up to lock in place for towing and swivels down to a stowed position, so there is no need to remove it for road use.

Instead of a fixed foot, the DLX-SW uses an 8 in diameter heavy-duty polypropylene slotted wheel that resists flat spots and cold-weather cracking. The wheel bracket rotates independently from the inner post, giving extra maneuverability when rolling the trailer tongue over sand, gravel, or uneven ramp surfaces. A side wind cushioned handle with an ergonomic grip and an extra heavy screw drive makes raising and lowering the tongue easier on the back. Drainage holes in the housing help shed water in marine environments, and the spring-loaded locking mechanism keeps the jack secure once positioned. The housing is finished in a powder coated matte black over zinc plating for corrosion resistance, and installation is complete bolt-on with no welding required.
