IMO home owners ought not be expected to be responsible for the container protecting some company's equipment. Sounds to me like yet another denial of responsibility by a commercial corncern and passing it onto a powerless citizen, who can like it or lump it. In any case whoever was responsible for the box being installed should have responsiblity for maintenance/repairs/replacement. But there should be an installer who is hireable to do the job. Again the home owner ought not have to know about repairing boxes.
