A cable management system includes elongated members mounted to a panel; and gate members configured to couple to at least some of the elongated members. Adjacent ones of the elongated members define management regions therebetween. Each gate member is rotatable relative to the respective elongated member to selectively inhibit and allow access to the respective management region. Each gate member can be fixed at any axial point along an adjustment region of the respective elongated member to adjust the depth of the management region.
