A high-quality galvanized sheet measuring 300 × 300 × 1 mm serves as a carrier for reflective plates on trucks, tankers, and trailers. It is equipped with a practical latch that prevents accidental release during operation. The galvanically galvanized sheet provides increased protection against corrosion and mechanical damage. The fastening system is compatible with standard reflective plates (e.g., ADR, speed limits, letter A). Simple and quick installation ensures reliable attachment even in challenging conditions.
