Locking side panels provide added security and also dress up the rack by hiding its contents, while powder-coated steel provides a durable fit and finish. Vents placed in the panel's bottom even allow for more efficient chimney-style exhaust ventilation. Smart design that anticipates all your integrated network needs. Believe it or not, some competitors' side panels require you to remove equipment from the bottom of the rack just to unlock and remove the side panels. Sound crazy; We thought so, too, and that's why we built a better mousetrap. Pins on the panels slide into keyhole slots, while a built-in handle lends a helping hand during installation and removal. Each side panel can easily be locked to prevent system tampering. Need to service or upgrade the equipment; No problem. Just unlock each panel with the included key and lift up. We've got vents in all the right places-the vents in the bottom of our side panels allow cool air to enter, and exhaust the hot air out of the top.
