Abstract: A leak containment system includes a mounting bracket, a tray, and a locking mechanism. The mounting bracket has a first rail, a second rail, and a panel extending between the first rails and the second rail. The panel is vertically offset from feet formed on the first rail, and a channel is defined by at least the first rail and an underside of the panel. The tray is removably received within the channel. The tray includes a bottom surface surrounded by perimeter walls that together define a fluid container. The perimeter walls include a front perimeter wall that extends upwardly above the other walls. The locking mechanism is coupled to the mounting bracket and is configured to selectively engage the front perimeter wall of the tray to restrict movement of the tray outward from the channel.
