text: The installation process is described as follows: a first or “upper” box, with an open bottom end facing downward, is embedded (along with at least one connected conduit) in the bottom at pour; a removable cover is temporarily attached (preferably, screwed) to the first box to cover its bottom end, prior to the pour, to prevent concrete from entering during the pour; the cover is removed after the pour to expose the open bottom end without having to break away concrete; and, a second or “lower” box, with a top end having an opening, is then lifted up and fastened (preferably, screwed) to the embedded first box.
