The Extron RSU 249 Universal Rack Shelf Kit for 2U, 9.5" Deep Products holds two GLI 2000 5BNCs. The 2U high rack is designed so that the underside of products mount to the shelf using the included hardware. When using a shelf mount rack, the user will see the front panel of each switcher, as it will be exposed in the rack. If only one device is needed, the included false front faceplate can be installed to eliminate gaps and maintain a professional appearance in the rack. Available in a gray powder coat finish.
