A slack loop manager is mountable to a network rack having a left side and a right side. The slack loop manager includes a first plurality of slack spools angled from the left side to the right side of the rack, and a second plurality of slack spools angled from the left side to the right side of the rack. The first plurality of slack spools are substantially parallel to the second plurality of slack spools. A divider is positioned between the first plurality and the second plurality of slack spools.
