Keson Industries MP401P 4 ft measuring wheel

Single-wheel measuring tool

The Keson Industries MP401P is a 4 ft circumference measuring wheel built for outdoor distance work. Its tubular steel frame and rubber-tread spoked wheel roll on uneven ground while the center-aligned handle folds down to a compact 21 in length. The counter records up to 99,999 ft in SAE units.

Who this suits and who it does not

Surveyors, landscapers and contractors who need quick linear measurements across sites will find the foldable 42 in extended handle convenient. Buyers who require metric readouts, indoor-only compact tools or electronic data logging should look at other instruments.

Deciding specification — wheel circumference

The 4 ft wheel circumference directly determines the distance recorded per revolution and the maximum reach of 99,999 ft. Confirm this increment matches the plotting or estimating scale used on the job before purchasing.
