Product Description

Open frame 4-post racks are the preferred choice for high-density server, networking, and AV equipment installations where ventilation and easy front and rear access are priorities. The R412-4530B provides 45 rack spaces of height with adjustable 4-post rail positioning at 12-inch and 24-inch depths, accommodating both shallow network gear and deep server or AV equipment in the same rack. The open frame design eliminates the thermal management challenges of enclosed racks and allows overhead cable management to be integrated without restriction. At 45SP, this is a full-height rack suitable for dense equipment builds in server rooms, data center colocation cabinets, broadcast technical areas, and enterprise MDF/IDF closets.
