A cable guide apparatus includes a first longitudinal channel defined by first, second, and third walls, the third wall toward and away from the first. The second and third walls may have a plurality of openings to facilitate bending of the longitudinal channel and any cables secured therein. The first wall may include a plurality of closure mechanisms, such as hooks, and the third wall may include a plurality of closure mechanisms, such as lips. The cable guide apparatus has an open condition in which cables may easily be inserted into the channel, and a closed condition in which the cables are secured in the channel. The width of the openings may define a maximum amount the cable guide apparatus may bend, such that cables secured within the apparatus do not bend to the point of being damaged.
