CNL 3U 19in TOOLLESS BLANKING PANEL Bk

The Cablenet CNL 3U 19″ Toolless Blanking Panel is a solid rack accessory designed to cover unused vertical space (3 rack units) in a 19″ network or server cabinet. It installs quickly without tools thanks to snap-in clips or toolless mounting hardware, helping maintain a neat and professional rack appearance. By blanking off unused areas, the panel improves airflow and cooling efficiency inside the rack by preventing hot air recirculation and reducing the risk of equipment overheating. Finished in black to match typical rack interiors, this panel is suitable for data centres, telecom closets, server rooms, and any environment with standard 19″ racks or cabinets.
