Radiopaque Light Field Centering Ruler

Another unique Radiopaque product from Supertech^®. This is a set of 444mm (17.467") '0' center rulers on a center pin. The center is designed to easily read all 222mm graduations in all directions from center, with no graduation overlap. 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.
