PROBLEM TO BE SOLVED: To provide a bracket having excellent strength and capable of supporting the load of an outdoor lamp fitting tool under hostile environmental conditions by providing a pair of vertical ribs extended to the outside at the opposite positions in the radial direction on the bracket. SOLUTION: This bracket assembly 10 contains a tubular bracket 16. The bracket 16 is generally formed into a curved or extended arch. The tubular bracket 16 is provided with the first upper opening end 18 and the second lower opening end 20. Since the bracket 16 is generally made tubular, a conduit is formed between the upper opening end 18 and lower opening end 20. A pair of ribs 32, 34 extended outward are extended along the length of the tubular bracket 16 from longitudinal side walls 24, 26. The ribs 32, 34 are extended from one opening end 18 to the other opening end 20 along the arch contour of the tubular bracket 16. The ribs 32, 34 are formed integrally with the tubular bracket 16 in an extrusion molding process. |
