Parallel mounting clamps with adjustable spindle GN 474.3 are used for adjusting measuring or test setups.
For coarse adjustments in millimeters, two adjacent clamping points are released so that the rod can be shifted quickly. When using retaining rods / retaining tubes GN 480.1 in type LS with longitudinal scale, their scale provides orientation during presetting.
For fine adjustments, two diagonally opposite clamping points are released. The relative position of the retaining rods/retaining tubes can then be set with the adjusting wheel. The adjusting distance can be read in 0.1 mm increments based on the knurled graduations. Due to the integrated spring, the adjustment is free of backlash.
