Economy Digital Rail Frog Wear Gauge  (does not roll through switches)

A worker can check hundreds of yards of track without having to bend and stoop every few feet to check gauge. Measure up to 2" of gauge variation (56" to 58" for standard gauge track). Insulated roller bearings provide smooth travel (will not go through switches or crossings). Side rollers contact rail 5/8" below head to avoid burrs, but yet pass over joint bars. Easy-to-read gauge scale (1/8" increments) can be read while walking. Scale can be calibrated to a specific gauge before starting out to inspect the track.

Frog wear measuring instrument is used for special measuring tools of railway line maintenance department for line frog and wing rail wear value. Wear-resistant measuring instrument, ruler-type frog wear measuring instrument,  digital display rail wear measuring instrument is suitable for the railway fixed frog fork ruler and the vertical wear amount and pile height of the wing rails on both sides, quickly measure the vertical and side wear of rail frogs.
