PURPOSE: Cable trays are provided to cost effectively implement producing processes and to simplify the processes by adopting a roll forming process. CONSTITUTION: Cable trays connect facing side rails(11, 12, 21, 22) with the end part of a transversal connecting member(3) using a fastening member(25). A through hole(27) passes through the peripheral part of the center of a shaft which is along the longitudinal direction of the transversal connecting member. The upper part of a cylindrical part is divided into two walls based on the center of the shaft. The upper part of the transversal connecting member is curved. The lateral part of the transversal connecting member is curved to form both bottom sides of the transversal connecting member. |
