ABSTRACT:
A fiber distribution terminal system includes a below ground vault, and a terminal enclosure within the vault. The system also includes a lift system in the vault, the lift system including a screw drive and a track system. Rotation of the screw drive lifts the terminal enclosure from a below ground to a lifted position, and the track system guides the terminal enclosure as the enclosure is lifted. The system also includes a tool such as a cordless drill to drive the screw drive. The screw drive can include a ball screw and a ball nut. The system can include a bracket to couple the terminal enclosure to the screw drive and the track system. The track system can include two sets of tracks, a first set of tracks that is fixed in the vault, and a second set of tracks that is coupled to the first set of tracks.
