Support assembly and cable management kit

A cable management kit comprising:

• a first cable management device comprising a first cross bar and a second cross bar movably connected to the first cross bar;
• and a second cable management device comprising a first cable management arm, a second cable management arm and at least one support bar, wherein one end of the second cable management arm is pivotally connected to one end of the first cable management arm, the at least one support bar is configured to support one of the first cable management arm and the second cable management arm;
• wherein the first cable management device is separated from the second cable management device, and the first cable management device, the second cable management arm and the first cable management arm are arranged in an order of the first cable management device, the second cable management arm and the first cable management arm, another end of the first cable management arm is detachably mounted to a first rail of a first slide rail assembly, another end of the second cable management arm is detachably mounted to a second rail of the first slide rail assembly slidable relative to the first rail of the first slide rail assembly, an end of the at least one support bar is detachably mounted on a first middle rail of the first slide rail assembly disposed between the first rail of the first slide rail assembly and the second rail of the first slide rail assembly, another end of the at least one support bar is detachably mounted on a third rail of a second slide rail assembly or a second middle rail of the second slide rail assembly disposed between the third rail of the first slide rail assembly and a fourth rail of the first slide rail assembly slidable relative to the third rail of the first slide rail assembly, the first cross bar is detachably mounted to the second rail of the first slide rail assembly, the second cross bar is detachably mounted to the fourth rail of the second slide rail assembly, when the second rail and the fourth rail move relative to the first rail and the third rail respectively, the first cross bar and the second cross bar move together with the second rail and the fourth rail respectively and do not move relative to each other, so that a length of the first cable management device is maintained and does not extend or retract.
