Does anyone know what this means? It is cited in the figure caption below the picture of the roller on page 34.
When doing the size check for the vertical expansion, if the expansion is touching the wall of the roller or can’t fit within the roller at all, then the expansion is illegal. The red box is merely saying the roller can be used to do a size check on vertical components.
