A cable carrier apparatus has a bracket having a vertical mounting surface interface for mounting securely to a post, wall, or other stable support, and a horizontal portion, a first roller rotatable on a vertical post anchored to be stationary relative to the frame bracket, with the first roller positioned below the horizontal portion of the bracket, the first roller having a circumferential groove symmetrical around an axis of the post and about a horizontal plane, the groove having a cross-section with a radius describing a portion of a semicircle, but less than a full semicircle, and a second roller matching the first roller and rotatable on a second post having an axis, the second roller mounted to be translatable against spring force away from the first roller, wherein a traveler translating on a cable being held between the two rollers traverses through the rollers, maintaining the cable between the rollers.
