摘要

The ring fixing (1) has a upper axial opening (4) in which is fitted the lighting column head. Blind holes (6) in the ring form an angle between 90 to 110 degrees with respect to a central hole (2) so that he lamp fitting arms make the same angle with the mast. A connector part is fitted between the mast and the ring (1). The connector part is fitted into an upper end of the mast and into the lower hole of the ring. Tubular lighting mast arm fixing ring. The hollow ring (1) has a lower axial opening (3), in which the upper end of the mast or a connector (11) is fitted, and one or more radial opening (5) in which lighting fitting arms are located. The ring has a central hole (2) and radial blind holes (6) opening out onto the central hole and closed at the exterior base (7). One or more of the blind holes are opened by cutting out the base (7) to form the radial holes (5) for the number of arms to be fitted at the mast head.
