Reference: Position of side bracket

Default position of side bracket at manufacturing is as follows.

  • Measurement position: Upper screw hole to magnet (horizontal) 4 brackets.

  • Nominal distance: 103.2 mm

  • Tolerance: +/- 2 mm

Note: The following illustration shows the jig at engineering. In the field, use the nonferrous tool if measurement is needed.
