Abstract: A locking member for locking panels having a frame, to a support structure. The locking member includes an elongated portion for fastening the locking member to the support structure, and at least one clip defined on the elongated portion for securing the frame thereto. The clip is configured for gripping the U section of the frame.

Abstract: Provided is an elongate construction element including a rigid elongate tubular body formed with at least one longitudinal U-like shaped groove. The groove is defined between a pair of facing side walls and a base wall spanning therebetween. The side walls are each formed with a plurality of parallely extending, spaced apart longitudinal ribs projecting therefrom, which together mimic a portion of a nominal threaded bore. The groove is formed such that the ratio between the height of the groove and the distance between the side walls is no greater than 1.8. The axial force in newtons necessary to remove a screw threaded therein the groove and fully penetrating the base wall is less than 3.7 times the product of the tensile yield strength of the material of the construction element and the distance between the sidewalls in millimeters.

Abstract: 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.
