A ladder-type cable tray (10) for cables or the like, the ladder including one or more pairs of L-shaped side rail members (11) having vertical and horizontal sides, the vertical side (12) having formed therein a protruding spring tab (14) disposed above a socket (16); and one or more U-shaped rung members (22) formed at either end with a flange (23) enclosing a U-shaped opening and defining a folded edge terminating in at least one tooth (24), the folded edge having formed therein a slot (26) for engaging the spring tab (14), such that upon insertion of the rung member (22) tooth into the socket on the side-rail (11), the spring tab (14) is deflected laterally and returns to its position to engage the locking slot (26) in the rung (22) and lock the rung to the side-rail (11), the locked rung (22) forming a support platform for the cable in a rigid fashion. |
