A cable support apparatus includes a flexible spine and a plurality of support members disposed along a length of the flexible spine. Each support member includes an attachment portion and a body portion. The attachment portion is secured to the flexible spine in at least two locations and cooperates therewith to define a first slot oriented in a first direction and a second slot oriented in a second direction perpendicular to the first direction. The body portion depends from the attachment portion, defines an interior, and includes an opening providing access to the interior. The opening is configured to permit passage of at least one cable therethrough and into the interior. The interiors of the body portions of the plurality of support members cooperate to define a longitudinal passageway extending along the flexible spine in parallel orientation relative to the flexible spine.
