Improve the organization & appearance of your rack while maintaining easy access & airflow, with a hinged blanking panel. The RKPNLHS2U 2U Hinged Solid Blank Rack Panel mounts to a standard 19" 2 or 4-post rack to improve the organization & appearance of your rack, while maintaining easy access & helping to guide airflow. The hinged blanking panel is reversible, meaning it can be installed to open from either the left or right side for easy access to the inside of your rack, while still covering the unused rack spaces for a professional look.
