APC 0M-3220 Assembly Blank Rectifier Cover, Black | Rack Accessory

Maintain a cleaner, more controlled rack environment by covering unused rectifier openings with the APC 0M-3220 assembly blank rectifier cover. In power and enclosure systems, small gaps can create unnecessary exposure, disrupt airflow patterns, and leave the installation looking unfinished. This blank cover helps close those openings with a part designed for the job. For infrastructure teams, details like this matter. A properly fitted blank cover supports a more disciplined rack layout, helps preserve the intended airflow path, and reduces the chance of accidental contact with open spaces in the assembly area. The black finish also keeps the installation visually consistent with surrounding equipment. This is the kind of accessory that earns its place in a premium deployment: simple, specific, and built to support the integrity of the larger system. When you are maintaining high-value power infrastructure, even a blank cover contributes to reliability, serviceability, and a cleaner operational standard.
