The set swings open for use and closes for storage in the case. The base ruler has a built-in stabilizer with clear rubber feet to keep its position on the image receptor.
A set of lines on the base helps the user quickly align the rulers at 90° to each other.
Felt bumpers keep the rulers from scratching each other.
