Abstract

A cable tray of the present invention comprises a pair of generally parallel spaced-apart metal side rails and metal rungs extending between the rails at intervals spaced along the rails. Each metal rung has opposite ends generally abutting respective side rails and a pair of preformed openings extending inwardly from the opposite ends of the rung lengthwise of the rung. A
pair of metal mechanical fasteners extend through the side rails and into respective preformed openings in the rung to fasten the rung to the side rails. Each of the openings is defined by a rung structure which, as viewed in a cross section taken transversely with respect to the rung, extends completely around the perimeter of the opening so that the perimeter of the opening is totally enclosed by the rung structure. Each of the fasteners is engageable with the rung structure defining a respective opening for securely holding the rung in fixed position with respect to its respective side rail.
