The tool-less mounting method attaches the cable management panel to the keyhole-shaped mounting holes that are built into your rack.The horizontal mounting rail method attaches the cable management panel to the horizontal mounting rails that run along the side of your rack.For racks that don't support these installation methods, you can also mount the cable management panels through other means, such as using the non-standardized holes found on your rack walls and enclosures, or the rack units on equipment mounting rails.Protect your equipmentRouting your cables through a panel reduces the tension that's often put on cables. This prevents cable damage or connection loss, and reduces strain on equipment ports, preventing damage to your expensive rack-mount devices.Properly routing cables also improves airflow, which passively cools devices stored in your rack, helping to keep your equipment running at optimal temperatures to reduce the probability of damage caused by your rack overheating.The CMVER20UD is backed by a StarTech.com 2-year warranty and free lifetime technical support.
