Siemon Company PNL-BLNK-1 | Patch Panel, 1 Unit, Black

Blanking panels and brush guard panels help to improve thermal efficiency by preventing airflow through vacant rack-mount spaces within enclosures. By isolating the front of the cabinet, these panels keep the cold air directed at the equipment where it is needed. Thermal blanking panels help to prevent recirculation of hot air to improve a facilitys cooling effectiveness. These panels also fill empty rack-mount space to conceal openings or reserve the positions for future use. Brush guard panels provide the added benefit of allowing cables to pass through the front and rear of a rack or cabinet while still providing thermal protection to maintain isolation.
