Prior to pouring the concrete floor, steel preset outlet boxes are installed at all locations where there will be an immediate or a future need for power, data, or telecom service. Preset outlet boxes snap into factory pre-punched openings in the cellular raceways – allowing cables to exit three individual raceways into each outlet box. Within the preset outlet box, power, data, and devices outlets are installed and cables are connected. Non-activated preset outlet boxes remain covered by a thin layer of concrete that is easily removed for future activation.
