A flanged, J-shaped bracket formed of sheet metal is provided in combination with a T-slotted downcomer (vertical channel), and creates an extremely strong support for heavy electrical cable. There is provided at the upper end of the bracket a connector element shaped generally as a hollow elbow having two portions. One such portion, the lower, is a very strong protuberance formed by making a deep recess in the web of the bracket. The underside of the protuberance seats on the bottom edge defining the T-slot, and bears large shear loads. The other such connector portion, the upper, is a tab inserted behind the upper edge defining the T-slot, and bears compression loads resulting from torque. The upper region of the protuberance fits relatively closely below the above-mentioned upper edge, thus causing the connector element to be immune to upward vibratory and other forces. The bottom surface of the protuberance is a rounded cam which greatly facilitates mounting of the bracket to the downcomer. In the web of the hook portion of the J is a bead which not only adds strength but aids in positioning the bracket in high-strength relationship. A part of this bead engages the downcomer and bears large compressive loads caused by torque. The hook portion of the bracket is well below the connector element, and this also is important to the achievement of proper torque and strength relationships.
