Identify Dutton-Lainson 22457, 22210, 22335 & Swivel Jacks

An 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.

Identify the original jack by MPN and construction

For the smaller marine models, 22457 is the 6400 with one 6-in wheel and 10 in travel. The 22210 is the standard DLx with an independent 8-in wheel, while 22335 is the premium DLx-P with a wider 8-in × 3-in wheel and additional protective covers. Both DLx models are 1,500 lb and have 12 in of travel.

The 22580 is the 6800 dual-wheel version: two 6-in wheels, 1,500 lb capacity and 12 in travel. The 22683 is the distinct 6634 agricultural/industrial model: topwind handle, steel foot, 2,000 lb rating, 15 in travel and weld-on bracket.

What to measure or inspect on the existing trailer

1. Find the complete MPN. Check labels on the jack's outer tube, retained packaging or previous maintenance records; do not identify by color alone.
2. Note the crank position. 22457, 22210, 22335 and 22580 are sidewind marine jacks. The 22683 is a topwind jack with a foot rather than wheels.
3. Count and measure wheels. Compare a single 6-in wheel, the 8-in DLx wheel, the extra-wide 8-in DLx-P wheel or the 22580's pair of 6-in wheels. Wheel size alone is not proof of series fit.
4. Check mounting style. Identify a bolt-on swivel bracket or the welded bracket of the 6634. Compare swivel-pin condition, bracket positions, frame size and installation clearance.
5. Measure actual lift needs. Compare the 10-, 12- and 15-in travel options with the trailer's coupler height. The manufacturer lists different maximum tongue heights and an overall height for 22683, so keep those measurements separate.
6. Check service condition. Inspect crank gears, swivel lock, corrosion, wheel axle and any grease fittings. Replace unsafe or damaged mounting hardware and follow the manufacturer procedure.
