An integrated lockable shelf rail configured to operate in pairs to support an electronic component is provided. The rail includes a front bracket to attach to a first vertical support and having a forward facing first plate, and a track assembly to be coupled to the front bracket. The track assembly includes a forward facing second plate to overlap with and couple to the first plate, a longitudinally extending C-shaped track member, and moveable arm arms slideably nested in the track member. The track assembly also includes a shelf bracket including a support surface to support the electronic component, a first side plate configured to couple to the second arm, and a forward facing third plate to overlap with the second plate. A hole in each of the first, second and third plates which, when the first, second and third plates overlap, collectively define a common hole to receive a fastener.
