Rocstor's Premium 1U 19in Cold Rolled Steel (CRS) Rackmount Cable Management Panel is an ideal solution to organize and manage network, server, and KVM cables in a standard 19-inch 2 or 4-post server rack. This cable management panel features a set of 5 removable 2.7-inch (68.5mm) tall ABS plastic D-ring hooks, spaced 4-inch (102mm) apart, to ensure that cable bundles are securely organized. In addition, the D-ring hooks at each end of the panel can be rotated to 90 degrees, allowing easy horizontal or vertical cable routing as per the requirement. By neatly organizing the cables, this 1U cable management panel provides strain-free cable connections between the rack-mounted devices while also improving airflow within the server rack to prevent the devices from overheating. Made of high-quality metal, this cable management panel is both strong and durable, capable of withstanding regular handling without bending or warping. The premium 1U 19in Metal Rackmount Cable Management Panel is backed by Rocstor's 2-year warranty and lifetime phone support.
