A mounting rail, particularly for use in building construction, is formed by an elongated rail member (2) of approximately C-shaped cross section having a rear wall (3) with spaced openings (7a-7d) therethrough and pair of side walls (4a, 4b) extending from and at substantially right angles to the rear wall (3). The side walls have free edge sections spaced from the rear wall bent inwardly towards one another and forming cross members (5a, 5b) extending generally parallel to the rear wall with the inner edges of the cross members spaced apart and forming a slot (6) extending in the elongated direction of the rail member (2). Each side wall (4a, 4b) has shaped recesses (8a, 8b) extending for the length of the rail member (2). The shaped recesses (8a, 8b) are arranged symmetrically to one another in the opposite sidewalls (4a, 4b) and have a depth of (d) which does not exceed the width (b) of the cross members (5a, 5b) defining the slot (6).

[ We claim:] [1.] A mounting rail for use in the building construction field, comprising an elongated rail member (2) having a length and an approximately C-shaped transverse cross section with a planar rear wall (3) extending in the elongated direction and having openings (7a-d, 27a-27c) extending therethrough and spaced apart in the elongated direction, said rear wall having a width (r) extending transversely of the elongated direction and a pair of laterally spaced side walls (4a, 4b) extending in the elongated direction and connected to and extending in a plane at substantially right angles from said rear wall, said side walls having a wall thickness, said side walls each having a free edge section extending in the elongated direction and spaced from said rear wall, said free edge sections bent inwardly from the plane of said side walls towards one another and each forming a cross member (5a, 5b) extending substantially parallel to said rear wall and perpendicular to said side walls and having inner edges disposed in spaced relation forming a slot (6) therebetween having a width (s) less than the width (r) of said rear wall extending in the elongated direction, each said cross member having a width (b) extending transversely of the elongated direction, said rail member having a partially closed interior formed by said rear wall and side walls, each said side wall having shaped recesses (8a, 8b; 18a, 18b; 28a, 28b; 38a, 38b; 48a, 48b;) extending for the length of the said rail member (2), said shaped recesses being arranged symmetrically to one another and having a depth (d) not greater than the width (b) of said cross members (5a, 5d) and said shaped recesses each having an opening in the plane of said side walls and extending inwardly from said side walls so that said openings face outwardly from the interior of said rail members.
