A cable manager includes a trough, defining a footprint, and a door. At least one side of the trough is formed from a plurality of finger-like projections extending forwardly from a support member. At least two of the projections include a hinge boss disposed at an outer end thereof and extending inwardly. At least one edge of the door has a hinge structure disposed therealong that includes an outer arm and an inner arm defining a hinge channel therebetween. The hinge bosses are disposed within the hinge channel such that the door is rotatably attached along at least one of its longitudinal edges to the trough. The door is rotatable to an open state without extending beyond the footprint of the trough.
