Battery-powered laser unit measures gauge to within 1/32″ accuracy.
Aluminum bracket with two rare-earth magnets holds Spot Check on rail.
Two adjusting screws raise or lower laser beam 20° with laser range of 135 feet.
Worker aims laser beam at a point 5/8″ below the head of the opposite rail and reads the gauge.
Spot Check makes it easier to check track gauge at intervals – previous readings are displayed as well as current readings.
