How is corner post side face outward deformation measured?

Corner post side face outward deformation is measured using a specific spacer to ensure accuracy in the assessment of the deformation. The choice of a 10mm spacer is appropriate because it provides a standardized distance that helps to clearly identify how much the corner post is bowing or bending outward from its original position.

Using this measurement method allows for consistency when comparing the deformation across different trailers, as manufacturers often set performance benchmarks around standard measurement tools. This 10mm spacer is thick enough to capture subtle deviations without compromising precision during the examination of the corner post's integrity.

The other possible measurement choices would not provide the same clarity or standardization, rendering them less effective for this specific evaluation of corner post deformation.
