Rail shoe with magnet & tubular level

The rail shoe is optimized for survey of the rail position. The reference for the side attachment is 14 mm below top of the rail with a notch to mark the measured position. The prism position is perpendicular above the reference edge. Two magnets for easy and safe positioning at the rail. Tubular level across the rail head for levelling the prism. Connection is a 5/8″ turnable male thread, others available on request.
