So my son is nearly walking, and we have an APC UPS unit (product link) in the living room, sitting on the floor, and tucked somewhat behind a TV stand. However, he is still small enough to get access to an end of the UPS and some of the power cords coming out. I'm trying to find a childproof box similar to this concept, but have not found any enclosures large enough to accommodate the UPS plus giving some extra height for plugs. I do have a last option, which is to put a fence around the TV stand; though my wife would rather avoid that look if at all possible.
