Engineered for precise film identification, the Aluminum L & R X-Ray Markers feature a rugged metal casing that enhances radiographic density, vertically oriented blue “L” and red “R” letters permanently sealed in crystal-clear epoxy for crisp visibility, and a compact footprint that positions neatly on cassettes or digital detectors—providing reliable, color-coded laterality marking that withstands the rigors of modern radiology workflows while cleaning easily between patients.
