A cable holder (10) including a frame (12) having a plurality of resiliently flexible trays (36) arranged in a column. A top surface (41) of one of the plurality of trays (36) and the bottom surface (43) of another of the plurality of trays (36) immediately positioned above it forms a pocket (P) that is sized and shaped to receive at least one cable (C), Each of the trays (36) includes at least one low rail (40) extending from the top surface (41) thereof, and the remainder of the trays (36) includes at least one high rail (42) extending from the bottom surface (43) thereof. A clip (28) is secured to the frame (12) for attachment to a bracket (58). The trays (36) are depressed to open the pocket (P), enabling insertion of one or more cables (C) therein or removal therefrom. The resiliency of the trays (36) along with the low rails (40) and high rails (42) deform the cables (C) to form slight bends therein to prevent side-to-side movement or slippage of the cables (C).
