Abstract

Communications cable management systems include a cable trough and a door that is configured to provide access to the cable trough. A first latch structure is attached to the door that includes a first latch and a second latch. A second latch structure is attached to the door that includes a third latch and a fourth latch. The systems also include a support structure that has first through fourth latch receiving assemblies that are configured to receive the respective first through fourth latches. The first through fourth latch receiving assemblies may comprise hinge brackets and/or pivotable latch members. The first and second latches and their corresponding first and second latch receiving assemblies are each configured to act as a hinge when the third and fourth latches are removed from their corresponding latch receiving assemblies. Similarly, the third and fourth latches and their corresponding third and fourth latch receiving assemblies are each configured to act as a hinge when the first and second latches are removed from their corresponding latch receiving assemblies.
