• feedthrough openings are provided, can be passed through the example, cables, wires or other elongated, band or cord-shaped elements. If such leadthrough openings are produced by punching out corresponding holes in the base section, then there is the problem that the edges of the leadthrough openings produced are relatively sharp-edged and when passing cables or lines their insulations are damaged or the elongate elements can be completely severed.
• the lead-through opening is arranged such that it extends over this distance, on the one hand the stiffness of the metal profile in this area is weakened and on the other hand an element guided through the lead-through opening can be formed in the channel formed between the two longitudinal sections of the channel Enter metal profiles. This is undesirable, as this can lead to jamming of the element and at the same time the risk of damaging the element is further increased.
• this object is achieved in that between the longitudinal sections a predetermined distance is present, that the distance from the connecting elements for connecting the longitudinal sections is partially bridged that at least one passage opening is provided in the base portion in that the lead-through opening extends from one of the longitudinal sections over the distance to the other longitudinal section and that at least one spaced-apart, two-part edge of the leadthrough opening is covered by a separate cover element extending along the edge of the one Longitudinal portion of the base portion extends over the distance to the other longitudinal portion.

• the cover advantageously has a substantially rectangular shape, whereby a simple overlap of the two-part edge of the passage opening is possible and at the same time by the cover a straight contact edge for the guided through the passage opening lines, cables or the like is formed.
• the cover element comprises a bent edge which extends over the distance and in particular has a rounded upper side. This design ensures that the insulation of a guided over the bent edge line, a cable or the like is not damaged while preventing hooking.
• the passage opening has a substantially rectangular, in particular a substantially square shape.
• the length of the Feedthrough opening in the longitudinal direction of the metal element substantially equal to the width of the passage opening including the distance between the longitudinal sections of the metal element.
• the passage opening comprises two two-part edges, wherein both edges are each covered by a cover.
• the two edges are opposite each other and preferably transverse to the longitudinal extent of the Metallpro fils. This ensures that, regardless of the installation direction of the metal profile in each case the lower edge of the passage opening is covered by a cover. Since cables, lines or the like routed through the lead-through opening normally rest on the lower edge of the passage opening, a protected support of the cables, lines or the like is thus achieved independently of the installation direction of the metal profile.
• a plurality of passage openings are formed in the base portion in particular at regular intervals. These can each be covered by a cover element designed according to the invention. As a result, the flexibility in performing the lines, cables or the like is further increased.
