Dutton-Lainson Trailer Tongue Jacks: Capacity, Lift & Wheels

A manual trailer tongue jack lifts and steadies the trailer at the coupler while hitching or parking. These Dutton-Lainson models span 1,000 to 2,000 lb rated jack capacity, but they do not all mount alike. Choose by supported tongue load, travel, frame mounting, crank location and whether you need a wheel or a steel foot.

Choose by mounting method and ground contact

Compact marine wheel jack22457 (6400) is a 1,000 lb, 10-in-travel bolt-on swivel jack with one 6-in polypropylene wheel. Its zinc-plated finish is intended for marine trailer exposure.
1,500 lb marine wheel choices22210 DLx has an 8-in independent wheel. The premium 22335 DLx-P uses an 8-in wheel that is 3 in wide. The 22580 instead uses two 6-in wheels.
Higher-capacity fixed foot22683 (6634) is a 2,000 lb, 15-in-travel agricultural/industrial topwind swivel jack with a weld-on bracket and steel foot, not a rolling caster.

Measurements have different meanings. Dutton-Lainson lists maximum tongue heights of 25 in (22457), 28½ in (22210 and 22335) and 28 in (22580). The 22683 has a separately listed 24¾-in overall jack height, not a stated maximum tongue-height rating in this comparison. Check the manufacturer's dimensional drawing for the actual mounting position.

The DLx 22210 and DLx-P 22335 are not identical trims: both have 1,500 lb capacity and 12 in of travel, but the DLx-P has a wider wheel, powder-coated inner and outer tubes, and protective covers. The 22580 differs again through its dual 6-in wheel configuration.

Before choosing or installing a jack

  1. Confirm the supported tongue load. A jack's lift capacity is not the gross trailer-weight rating; select the jack for the load it will actually support with the correct safety margin.
  2. Check the mount. The four marine models here use bolt-on swivel brackets and the manufacturer specifies suitable square trailer tongues up to 3 × 5 in. The 22683 requires a weld-on bracket and qualified installation.
  3. Measure the required height and lift. The rated travel is 10, 12 or 15 in depending on the model. Also check coupler height, full mounting clearance and ground contact; do not treat overall jack height as maximum tongue height.
  4. Choose the ground-contact style. A single 6-in wheel, standard 8-in wheel, 3-in-wide 8-in wheel, dual 6-in wheels and fixed steel foot address different surfaces and manoeuvring needs.
  5. Check clearance before swivelling. Allow space around the tow vehicle, frame, coupler, handle and wheel or foot. Fully stow and lock the jack for travel; never tow with a load carried on the jack.
  6. Follow the exact manufacturer's instructions. Verify the supplied mounting hardware, swivel lock, tightening and lubrication for the selected MPN. Do not assume replacement wheel or bracket compatibility across models.

A tongue jack handles parked-trailer support, while winches and tie-downs serve other jobs. See our Dutton-Lainson manual winch comparison and BoatBuckle transom tie-down selection. These are not interchangeable mounting systems.
