Overview The APC AR8136WHT200 is a pack of 200 modular toolless blanking panels designed to seal unused 1U spaces in 19-inch racks. These panels help optimize airflow by preventing hot exhaust air from recirculating to the front of the rack, ensuring that servers and switches receive cooler intake air and operate more efficiently. Each panel weighs just 3.2 ounces and snaps into place without the need for tools, making installation quick and hassle-free during rack build-outs or equipment rearrangements.
