The 1 RU, 5 ring cable management panel is typically used to guide and locate various cables going to rack-mounted transmission equipment. This lightweight and strong design can safely and neatly hold many cords in the five, openable style, guiding/securing clips provided. The Guide Unit ensures maximum space is available in the rack for the cooling air stream. The Guide Unit fits a 19" rack. However, extension brackets, for 21” and 23” mount are available separately. If required, hook and loop style ties available separately.
