A waterfall-type cable router for routing cables out of cable trays includes a curved ramp having a front portion and a rear portion, a vertical left curved wall transitioning into the curved ramp and extending the length of the left side of the curved ramp, and a vertical right curved wall transitioning into the curved ramp and extending the length of the right side of the curved ramp. The rear portion of the curved ramp curves outwardly such that a distal end of the rear portion may be wider than a distal end of the front portion of the curved ramp.
