The epoxy coating resists corrosion to ensure long-lasting use, and it is suitable for use in dry, humid, or moist environments, making the unit a multi-purpose investment that's sure to accommodate your ever-evolving needs. Because the coating is black, it's subtle and professional, perfect for office settings or for merchandising applications and front-of-house sales. Plus, the included 5" casters allow for quick access and easy cleaning, and the casters are equipped with brakes to secure the unit in place when needed.
