A substantially S-shaped side frame for a roller conveyor has a first duct section defining an exterior opening and a second duct section defining an interior opening. Necessary operating components, such as controllers, and associated wiring may be installed in the first duct section. Roller shaft support brackets are installed across the interior opening with a certain longitudinal pitch. The shafts of a plurality of laterally extending rollers are installed in through holes provided in the brackets to define a conveyor path for transporting articles. The brackets each include opposed slots for mounting to opposed rails for the second duct section. The opposed slots in the brackets include an inwardly tapered portion that allows the brackets to be rotatably inserted between the opposed rails. Each bracket may include one or more through holes for stably supporting the roller shafts. Each through hole is defined by a first through aperture (horizontal) and a second through aperture (vertically angled) that intersect in the bracket.
