Abstract: A communications cable management system includes a support structure and a door assembly. The support structure defines a cable trough and includes at least two first mount structures and at least two second mount structures spaced apart from the at least two first mount structures. The door assembly includes a door body, first and second latch mechanisms, and first and second actuators. The door body has first and second opposed side edges. The first latch mechanism includes at least two first latch structures each selectively positionable between a latched position, wherein the first latch structure engages a respective one of the first mount structures to secure the door body to the support structure for pivotal movement therebetween about a first pivot axis proximate the first side edge of the door body, and an unlatched position, wherein the first latch structure is disengaged from the first mount structure to permit the first side edge of the door to be separated from the support structure.
