Abstract: A cable tray system comprising a cable tray for carrying cable, a support fastened to the cable tray, and at least one cover panel operatively associated with the support for covering cable carried by the cable tray. The cover panel is engageable with the support for pivoting about an axis generally parallel to a longitudinal axis of the cable tray between an open position in which the cover panel is swung up and away from the cable tray to permit access to cables in the tray and a closed position in which the cover panel is swung down to cover cables in the cable tray. The cover panel is removable from the support without removing the support from the cable tray.
